Fig. 2 is the cutaway view of the reaction unit 10 of the 1st embodiment of the present invention.

The 1st reacting part 11 and the 2nd reacting part 12 are accommodated in the thermally insulated container 30 described later.Between the 1st reacting part 11 and the 2nd reacting part 12, be provided with pipe arrangement 21 (with reference to Fig. 2) as the stream of reactant and product.In addition, in the 2nd reacting part 12, be provided with and be used for the pipe arrangement 22 (with reference to Fig. 2) that makes reactant outside thermally insulated container 30, flow into or make product outside thermally insulated container 30, to flow out.

The 1st reacting part the 11, the 2nd reacting part 12 and pipe arrangement 21,22 for example also can fit metallic plates such as stainless steel (SUS304) or Kovar alloy and form, and perhaps also applying such as glass substrate can be formed.

Then, the thermally insulated container 30 of taking in the apparatus main body portion 20 that responds is described.Thermally insulated container 30 forms rectangular shape, has taken in the 1st reacting part 11 and the 2nd reacting part 12 in the inside.The 1st reacting part 11 is connected by pipe arrangement 21 with the 2nd reacting part 12, and the 1st reacting part 11 and the 2nd reacting part 12 are fixing by the pipe arrangement 22 that connects thermally insulated container 30.

The casing 31 of thermally insulated container 30 can be by forming applyings such as metallic plates such as stainless steel (SUS304) or Kovar alloy or glass substrate.The inner space of thermally insulated container 30 is maintained low pressure (0.03Pa is following) for the heat conduction that prevents gas molecule and convection current.

In addition, on the internal face of casing 31, in order to suppress the thermal loss of bringing from the radiation of reaction unit main part 20 and be formed with the thermal reflecting coating 32a of reflected infrared ray (heat ray).In thermal reflecting coating 32a, shown in Figure 7 as described later, can use for example higher metals of infrared reflection rate such as gold (Au), aluminium, silver or copper.Thermal reflecting coating 32a can be by being formed these metal film forming by vapor phase methods such as sputtering method or vacuum vapour depositions.In addition, forming under the situation of thermal reflecting coating 32a, layers such as chromium, titanium also can be set in substrate as connecting airtight layer with gold.

Thus, can suppress from the thermal loss of reaction unit main part 20 to the outside of thermally insulated container 30.

Because heat is transmitted to the 2nd reacting part 12 from the 1st reacting part 11 via pipe arrangement 21, so if conducted via pipe arrangement 22 and be transmitted to heat more than the heat of thermally insulated container 30, then temperature might rise to more than the suitable temperature.So, on the internal face of the thermally insulated container 30 of the present embodiment, be provided with heat radiation promotion portion 40 corresponding to the position of the 2nd reacting part.

Heat radiation promotion portion 40 compares the high zone of ultrared absorptivity with other zones of the internal face of casing 31, absorbs the infrared ray from 12 radiation of the 2nd reacting part, and makes it as heat and thermally insulated container 30 is given in heat conduction.Thus, can increase by from the radiation of the 2nd reacting part 12 and the heat (heat leak) of dissipation, the temperature that can reduce by the 2nd reacting part 12 rises.

Heat radiation promotion portion 40 can absorb ultrared heat absorption film 32b and forms for example as shown in Figure 2 by being provided with in the inboard with the opposed thermal reflecting coating 32a of outside wall surface that pipe arrangement 21,22 is not set of the 2nd reacting part 12.

Below, to studying as the material of heat absorption film 32b and thickness etc.

(1) research of reflectivity

At first, the reflectivity of heat radiation promotion portion 40 is studied.

Fig. 3 is the curve chart (20%～90% o'clock curve calculates based on 10% o'clock value) that expression makes heat radiation promotion portion 40 pairs of ultrared reflectivity relation of area during every variation 10%, heat radiation promotion portion 40 and heat leak (calculated value) between 10%～90%.Here, suppose that the absorption coefficient of heat absorption film 32b is enough big, and do not have the overheated absorbing film 32b of transmission, the overheated absorbing film 32b of transmission and get back to infrared ray in the thermally insulated container 30 once more by substrate or thermal reflecting coating 32a reflection.

In addition, the size of the 2nd reacting part 12 is set at 1.0cm * 2.5cm * 0.3cm, and the 2nd reacting part 12 is 0.5cm with the distance setting of thermally insulated container 30.In addition, go into and go out all to be set at 0.90W from the hot-fluid of pipe arrangement 22 from the hot-fluid of pipe arrangement 21, the initial temperature of the 2nd reacting part 12 is set at 120 ℃.

Change from the heat of heat radiation promotion portion 40 dissipations reflectivity according to heat radiation promotion portion 40 by radiation, and proportional with its area.So the promotion portion 40 of will dispelling the heat is set at suitable reflectivity and area by the heat of considering the dissipation by radiation, can make the Temperature Distribution of reaction unit main part 20 become the state of expectation.

For example, can learn, be under 10% the situation at the reflectivity of heat radiation promotion portion 40, is 4.0cm at the area of heat radiation promotion portion 40 ²Situation under, heat leak is about 0.35W, the temperature of the 2nd reacting part 12 descends about 40 ℃ and become about 80 ℃.

This heat radiation promotion portion 40 forms rectangular-shaped in the present embodiment, and the area of heat radiation promotion portion 40 is for example identical with area corresponding to the side of the 2nd reacting part 12.

(2) research of absorption coefficient and thickness

Then, absorption coefficient and the thickness of the heat absorption film 32b when on the substrate of casing 31 or thermal reflecting coating 32a heat absorption film 32b being set as heat radiation promotion portion 40 are studied.

Fig. 4 is expression incident, reflects, is transmitted to the schematic diagram of the ultrared relation among the heat absorption film 32b.

Here, as shown in Figure 4, if the distance (degree of depth) that the absorption coefficient that establishing the ultrared intensity that incides among the heat absorption film 32b is I, establish ultrared intensity by the surface reflection of heat absorption film 32b is R, establish heat absorption film 32b is α, establish apart from the surface of heat absorption film 32b is t, then the ultrared intensity I (t) of the overheated absorbing film 32b of transmission of the position of distance (degree of depth) t is represented by following formula.

I(t)＝(I-R)exp(-αt)

The relation of t and I (t)/(I-R) (=exp (α t)) when expression α is set at 10000/cm, 30000/cm, 60000/cm, 100000/cm among Fig. 5.

Under the situation of α=100000/cm, the about 230nm of t=, the ultrared intensity of the overheated absorbing film 32b of transmission is less than 10%.That is, if α is t＞about 2.3, then the ultrared intensity of the overheated absorbing film 32b of transmission is less than 10%, and then, the overheated absorbing film 32b of transmission and get back to infrared rays in the thermally insulated container 30 for less than 1% by substrate or thermal reflecting coating 32a reflection and once more.Thereby thickness T is that the film of α t＞about 2.3 is fit to as heat absorption film 32b.

On the other hand, under the situation of α=100000/cm, t=25nm, promptly under the situation of α t=0.25, the ultrared intensity of the overheated absorbing film 32b of transmission is about 78%, and then, overheated absorbing film 32b of transmission and the infrared rays got back in the thermally insulated container 30 are 61% once more by substrate or thermal reflecting coating 32a reflection, so be unaccommodated as heat absorption film 32b.

(3) research of radiation wavelength

Then, to studying from the wavelength of reaction unit main part 20 radiation.Fig. 6 is the curve chart of the relation of the wavelength of black body radiation of expression 300K (27 ℃), 600K (327 ℃), 900K (627 ℃) and radiation density.Can learn that radiation density uprises when (below the 0.6eV) more than 600K, wavelength are 2 μ m, radiation density uprises when (below the 1eV) more than 900K, wavelength are 1.24 μ m.Thereby requiring 40 pairs of wavelength of heat radiation promotion portion is that the above ultrared reflectivity of 1.24 μ m is lower.

(4) research of metal material, semi-metallic

Metal material, the general reflectivity of semi-metallic are higher, and absorption coefficient is more than the 105/cm under nearly all wavelength, can be 230nm and as the candidate of heat absorption film 32b by making thickness.So, the reflectivity of metal material, semi-metallic is studied.

The reflectivity of representing Au, Al, Ag, Cu, Rh among Fig. 7 to wavelength.Wherein, in the wavelength region may more than 1.24 μ m, the reflectivity of Rh is lower, can be used as the candidate of the material of heat absorption film 32b.

In addition, as the lower metal of reflectivity when the wavelength of 1.24 μ m, can be with the material as heat absorption film 32b such as Fe (reflectivity is 75%), Co (reflectivity is 78%), Pt (reflectivity is 78%), Cr (reflectivity is 63%).

In addition, as semimetal and the material of antiradar reflectivity has graphite (stratiform carbon).The reflectivity of graphite is 42% when wavelength is 1.24 μ m, is 47% when wavelength is 2 μ m, is less, can be used as the material of heat absorption film 32b.In addition, be called relatively poor, the also disorder of bedded structure of material with carbon element crystallinity of active carbon, but also can be with its candidate as the material of heat absorption film 32b.

In addition, in any metal film of Au, Al, Ag, Cu, Rh, be that the reflectivity of the infrared ray (wavelength is 5～30 μ m) that produces in the temperature province of hundreds of ℃ is roughly 100% at the operating temperature of the 1st reacting part 11.Therefore, any metal film of Au, Al, Ag, Cu, Rh all is suitable as thermal reflecting coating 32a.

(5) research of nonmetallic materials

Semiconductor mostly in the wavelength region may more than light wavelength is 1.24 μ m reflectivity be 10～20% or below it, can think to be suitable as the material of heat absorption film 32b, but almost in all cases, absorption coefficient is less than 1/cm, and is very little.

But the absorption coefficient of amorphous semiconductor with dangling bonds (dangling bond) is higher, it is believed that the material that can be used as heat absorption film 32b uses.For example, in having the amorphous silicon of a fairly large number of suspended chain, absorption coefficient is more than the 1000/cm, can be used as the material of heat absorption film 32b.

In addition, as heat absorption film 32b, Ta-Si-O-N class film is arranged in the amorphous semiconductor material that is more suitable for.Expression is the Ta-Si-O-N class film of 1.0m Ω cm, 5.5m Ω cm for resistivity among Fig. 8, and (wavelength is the absorption coefficient (cm under about 2.48 μ m～350nm) to measure 0.5～3.5eV ^-1) the result.Resistivity is that film absorption coefficient in this measuring range of 1.0m Ω cm can be used as the material of heat absorption film 32b for more than about 100000/cm.

And then the applicant finds, is the Ta-Si-O-N class film of composition of the scope of about 0.6＜Si/Ta＜about 1.0 and about 0.15＜N/O＜about 4.1 for mol ratio, is 2.5m Ω cm when following in resistivity, and absorption coefficient is for more than about 100000/cm.Thereby described material also can be used as the material of heat absorption film 32b.

As described above, according to the present embodiment, can promote from the more heat radiation of the reacting part of low temperature, can guarantee the temperature difference between the reacting part of the reaction unit that constitutes by two above reacting parts.

[variation 1]

In described embodiment, by heat absorption film 32b is set heat radiation promotion portion 40 is set on thermal reflecting coating 32a, but also can be as shown in Figure 9, by the opening portion that substrate that thermal reflecting coating 32a forms thermally insulated container is exposed is not set on the part of the inner surface of casing 31, with this opening portion as heat radiation promotion portion 41.At this moment, the reflectivity of opening portion is the reflectivity of casing 31.

In addition, be under the situation of glass substrate at casing 31, casing 31 is crossed in the most of transmission of infrared ray.Therefore, the reflectivity of opening portion is compared relatively lower with the casing 31 that is not opening portion with the reflectivity of thermal reflecting coating 32a superposed part.

[variation 2]

Perhaps, also can be as shown in figure 10, on whole of the internal face of casing 31 heat absorption film 32b is set, and on heat absorption film 32b thermal reflecting coating 32a is set all except a part, the opening portion that this heat absorption film 32b is exposed is as heat radiation promotion portion 42.

[variation 3]

In addition, also can be as shown in figure 11, on the part of the internal face of casing 31, heat absorption film 32b is set, and on other parts of the inner surface of thermally insulated container, thermal reflecting coating 32a is set, the opening portion that heat absorption film 32b is exposed is as heat radiation promotion portion 43.In the case, the peripheral part of heat absorption film 32b is overlapped with a thermal reflecting coating 32a part.

[variation 4]

In addition, if the reaction temperature of reaction unit main part 20 surpasses 600 ℃, the then increase of radiation density become significantly (with reference to Fig. 6).Thereby thermal reflecting coating 32a one deck is inadequate, can consider to make two-layer structure.That is, as shown in figure 12, separate space 33 and the 2nd thermal reflecting coating 34 is set in the inboard of the thermal reflecting coating 32a in the outside.Space 33 is for example formed by the support component 36 that constitutes with casing 31 identical materials.By separating space 33, can prevent from of the heat conduction of the 2nd thermal reflecting coating 34 to the 1st thermal reflecting coating 32a, improve adiabatic efficiency.

In the case, as shown in figure 13, heat radiation window 35 can be set on the position corresponding to the 2nd reacting part 12 of the 2nd thermal reflecting coating 34 also.Only prevent by radiation,, promoted the heat radiation of the 2nd reacting part 12 so compare with the 1st reacting part 11 that prevents radiation by two-layer thermal reflecting coating 32a, 34 by the thermal reflecting coating 32a in the outside with heat radiation window 35, the 2 reacting parts 12.

[variation 5]

In described embodiment, be provided with heat radiation promotion portion 40～43 with the internal face of the opposed casing 31 of outside wall surface that pipe arrangement 21,22 is not set of the 2nd reacting part 12, but also can regulate by the heat dissipation capacity that radiation produced by the area of increase and decrease heat radiation promotion portion 40～43 from the 2nd reacting part 12.

Then, if flow in the conversion reaction chamber 161 by reaction supply port 123e and the stream 162 of giving row portion 123, then generate hydrogen etc. by reforming catalyst 165 by the fuel of gasifier 150 gasifications and the mist of water vapour.

At this moment, conversion reaction chamber 161 is applied the heat that is produced by thin film heater 505a, the reaction heat (combustion heat) that reaches generation in combustion reaction chamber 181 etc.In addition, from the heat ray of the interior side direction direction radiation toward the outer side of reaction unit main part 120 by the thermal reflecting coating 132a of first substrate 300 and the 5th substrate 700 to internal reflection.As a result, conversion reaction chamber 161 becomes than higher temperature, and reforming catalyst 165 is heated to 200～400 ℃, is heated to about 300 ℃ in the present embodiment.

In addition, the conversion reaction in the conversion reaction chamber 161 is undertaken by the water vapour conversion method in the present embodiment, but also can be undertaken by the partial oxidation conversion method.

Then, the hydrogen of generation etc. enter into carbon monoxide and remove stream 171 by being communicated with stream 163, and mix from the auxiliary supply port 123c leaked-in air of the oxygen of giving row portion 123.So the carbon monoxide in the mist is removed catalyst 175 oxidations, is removed by carbon monoxide.

In addition, converter 160 and catalytic burner 180 physically link up via the circuit portion of linking part 121 with carbon monoxide remover 170.But, between converter 160 and catalytic burner 180 and carbon monoxide remover 170, be provided with adiabatic chamber 139b.Therefore, cut down the sectional area of linking part 121 between the two, suppressed to transmit heat to carbon monoxide remover 170 from converter 160 and catalytic burner 180.

On the other hand, the heat of the inside of reaction unit main part 120 via the peristome 141 that is arranged on the thermal reflecting coating 132a on first substrate 300 and the 5th substrate 700 to outside dissipation, so the temperature of carbon monoxide remover 170 reduces.As a result, between converter 160 and carbon monoxide remover 170, be provided with appropriate temperature difference.

Thus, carbon monoxide remover 170 is set to lower temperature with respect to converter 160, and carbon monoxide is removed catalyst 175 to be become 120～200 ℃, become about 120 ℃ in the present embodiment.

Then, if supply air to the oxygen utmost point of generator unit 103, and the mist of carbon monoxide being removed hydrogen in the stream 171 etc. is discharged and is supplied to the fuel electrodes of generator unit 103 from the reaction outlet 123d that gives row portion 123, then generates electric energy in generator unit 103.

Then, the mist (tail gas) that comprises unreacted hydrogen in the fuel electrodes of generator unit 103 flow in the combustion reaction chamber 181 by fuel supply mouth 123a and the stream 183 of giving row portion 123, and air flow into the combustion reaction chamber 181 from the outside by fuel oxygen supply mouth 123b and the stream 183 of giving row portion 123.Then, hydrogen burning in combustion reaction chamber 181 and produce the combustion heat is discharged the product of water and carbon dioxide etc. from the fuel discharge outlet 123f that gives row portion 123 via stream 182 to the outside.

Reaction unit 110 according to above fuel-cell device 101, owing to being provided with converter 160 and carbon monoxide remover 170 via being communicated with stream 163 between second substrate 400 and the 3rd substrate 500, the situation in the past that is linked by connecting piece etc. so be provided with independently with converter 160 and carbon monoxide remover 170 is different, can make the device integral miniaturization.

In addition, because can be when staying the heat of the inside of reaction unit main part 120 in the inside by thermal reflecting coating 132a, to outside dissipation, in reaction unit main part 120, form suitable Temperature Distribution via the peristome 141 in the zone corresponding so can reduce the temperature of carbon monoxide remover 170 with carbon monoxide remover 170.Thereby, even make 120 miniaturizations of reaction unit main part,, also can in converter 160 and carbon monoxide remover 170, will be made as only temperature separately, carry out separately reaction well the situation that converter 160 and carbon monoxide remover 170 more closely disposes.

In addition, converter 160 and carbon monoxide remover 170 are set in reaction unit main part 120 communicatively by stacked first substrate 300～the 5th substrate 700, so different with making converter 160 and carbon monoxide remover 170 respectively with the situation in the past of bindings such as connecting piece, once produce reaction unit main part 120.In addition, because reaction unit main part 120 forms with thermally insulated container 130, so set the situation of reaction unit main part 120 in the inside of thermally insulated container 130 with making reaction unit main part 120 and thermally insulated container 130 respectively different, once produce reaction unit 110.Thus, can cut down the manufacturing process of reaction unit 110.
