Embodiment

Figure 1A shows that this creation is used for the profile of the condenser of fuel cell (1).Figure 1B is the cross sectional side view of this creation condenser (1) of being used for fuel cell.With reference to Figure 1A and Figure 1B, this creation condenser (1) is to comprise housing (10) and at least more than one heat sink (12) simultaneously.Wherein, housing (10) is a kind of enclosed construction with internal capacity room (100), and housing (10) has air inlet (102), exhaust outlet (104) and at least more than one delivery port (106).Housing (10) for example can adopt the enclosed construction of box.Air inlet (102) is the outlet that directly connection or caliber are connected to the gaseous state product of fuel-cell device (not shown).In addition, air inlet (102) is the sidewall that can be arranged on housing (10), and exhaust outlet (104) is the upper wall that can be arranged on housing (10).

Moreover shown in Figure 1B, this creation condenser (1) adopts pits rampway structure (108) in the bottom of internal capacity room (100) especially, and delivery port (106) is to be arranged at the end of pits rampway structure (108) than downside.Pits rampway structure (108) and delivery port (106) purpose is set, can lift the direct methanol fuel cell device and be used as the example explanation, the steam that the direct methanol fuel cell device generated is to enter in the inside of condenser (1) from air inlet (102).When steam is subjected to the thermolysis of those heat sinks (12), and when condensing into liquid water, condensate can depend on pits rampway structure (108) and take advantage of a situation to flowing than downside, flows out to the outside of condenser (1) then from delivery port (106).Certainly, the condensate that is reclaimed can be the fuel cell utilization again.

And for example shown in Figure 1A and Figure 1B, heat sink (12) for example can adopt the structure of radiating fin, and heat sink (12) can be arranged at the internal capacity room (100) of housing (10) by the first-class execution mode of inwall that is arranged at housing (10).Shown in Figure 1A, this creation condenser (1) can further comprise for another example: gas-permeable, liquid-impermeable film (110).Gas-permeable, liquid-impermeable film (110) is to cover exhaust outlet (104) tightly, and is fixed in housing (10).By above setting, the steam that the direct methanol fuel cell device is generated is can be in internal capacity room (100) unobstructed to move and is uniformly distributed in each zone.

Then, please refer to shown in Figure 2.Fig. 2 amplifies the inner wall surface structure chart that shows this creation middle shell (10).The inwall of housing (10) is to have flow guiding structure (112), and flow guiding structure (112) can adopt the irrigation canals and ditches structure (1120) more than at least one.For the inwall that makes housing (10) has preferable drainage effect, the width W scope that irrigation canals and ditches structure (1120) is gone up in common enforcement is between 0.2 millimeter to 1 millimeter, and the depth D scope of irrigation canals and ditches structure (1120) is between 0.2 millimeter to 2 millimeters.Certainly, flow guiding structure (112) on the inwall of housing (10) is not only to be defined in irrigation canals and ditches structure (1120) shown in Figure 2, it also can be changed to the metal wire structure more than at least one, or at least more than one microparticle structure etc. other have the structure of drainage effect equally.

Fig. 3 is the cross sectional plan view of an alternate embodiment of this creation condenser (3).As shown in Fig. 3, heat sink (32) is to be arranged on the inwall of housing (30) equally, but the part of heat sink (32) is the internal capacity room (300) in housing (30), and another part of heat sink (32) then is arranged at the outside of housing (30).Moreover this creation condenser (3) can further comprise cooling fan (34), and cooling fan (34) is the outside that is arranged at housing (30), and towards heat sink (32) in housing (30) outside that part.So, cooling fan (34) just can be assisted the radiating effect that quickens heat sink (32), causes heat sink (32) that bigger temperature difference is arranged, and promotes the condensation effect of this creation condenser (3).

In order to make this creation condenser have preferable condensation effect, the material of the housing of condenser (10), (30) can use heat conducting material (for example: metal material) make.In addition, the fuel-cell device that is applicable to this creation condenser can be single fuel cell or fuel cell pack (stack).

This creation condenser can be in order to be condensed into water with the steam that fuel-cell device generated, and the steam of being caught all is limited in internal capacity room (100), (300) of condenser, and can not allow the steam that fuel-cell device generated be discharged arbitrarily, this is the advantage place of this creation.

Another characteristic of this creation are the design of the flow guiding structure (112) of the pits rampway structure (108) of internal capacity room (100) bottom and housing (10) inwall.The liquid water droplets that above-mentioned design makes steam condense into can utilize the capillarity of flow guiding structure (112) and the gradient of pits rampway structure (108) itself to quicken to form condensate, thereby significantly shorten condenser and carry out the required time of condensation operation, the place of the another advantage of this that is this creation.

Though this creation discloses as above with specific embodiment; right its disclosed specific embodiment is not in order to limit this creation; anyly be familiar with this technical staff; in the spirit and scope that do not break away from this creation; when being used for a variety of modifications and variations; its change of doing all belongs to the category of this creation with retouching, the protection range of this creation when according to the application claim defined is as the criterion.
