ガスの利用率を著しく向上させることができる。In this way, in contrast to the conventional phosphoric acid fuel cell, where the gas was removed once in one direction and therefore contributed only once to the reaction within the cell, the phosphoric acid fuel cell according to this embodiment The device was configured so that fuel gas or oxidant gas made 15 reciprocations between a gas inlet (51) provided at one end in the direction of the electrode surface and an outlet (52) provided at the other end. Therefore, it can contribute three times to the reaction in the battery,
The gas utilization rate can be significantly improved.

性の向上、あるいは信頼性が向上する。In addition, in the above embodiment of the present invention, a porous carbon plate (
2) has an average pore diameter of 3 to 5μ and a porosity of 50 to 80%.
Moreover, since no adhesive is used between the separator (1) and the porous carbon plate (2), the adhesive oozes out and causes damage to the porous carbon plate (2).
), there is no risk of clogging the inside (i.e., pores) or the flow path (3), and the oxidant gas and fuel gas can sufficiently flow in and diffuse in the direction of the gas flow path (3) and in the direction perpendicular to the gas flow path, and the battery Improved characteristics or reliability.

が６０〜７０％程度のものを用いることは望ましい。Note that the larger the average pore diameter and porosity of the porous carbon plate (2), the better the gas diffusion in the direction perpendicular to the gas flow path, but this is subject to limitations in terms of mechanical strength and battery life. Therefore, it is desirable to use a material with an average pore diameter of 5 to 20 microns and a porosity of about 60 to 70%.

料ガス中のＮ２濃度が低く、Ｎ２ガス量も少なく、燃料
ガス出口側の酸化側電極が腐食する虞れがある。The following is an example of how the gas flow path of the phosphoric acid fuel cell of the above embodiment can improve the gas composition of the entire reaction surface within the cell, as well as the current density distribution and temperature distribution, using the fuel gas flow path as an example.9 Population Composition is N2: When fuel gas with N2 = 80.20 is passed through the fuel gas flow path of a conventional fuel F4 battery at a gas utilization rate of 80%, the outlet composition is N2.N2 = 1.6:20, and the N2 in the fuel gas is Since the concentration is low and the amount of N2 gas is small, there is a risk that the oxidation side electrode on the fuel gas outlet side will corrode.

。On the other hand, when a fuel gas having a composition of N2:N2=8020 is similarly flowed at a gas utilization rate of 80% through a fuel cell using the gas flow channels of the above example, the average of the three gas flow channels is The composition is H2:N2=155:60, and the outlet composition is N2・N2=133:60. The composition of the input and exit loops is N.
2+N2=approximately 144.60, indicating that the gas composition distribution is uniform and the amount of N2 gas is sufficient on the outlet side, eliminating concerns about corrosion of the oxidizer electrode.

), whereas in this example N2:N, = 1

減にも貢献できるものである。Although the fuel gas flow path has been described above, the oxidant gas flow path also provides similar effects. Overall, the gas composition distribution within the reaction surface within the battery, as well as the current density distribution and temperature distribution, have been made uniform, making it possible to improve battery characteristics and extend the lifespan, and to ensure reliability without worrying about electrode corrosion. A highly efficient fuel cell device can be obtained. Furthermore, since the structure of the present invention is simple, it is suitable for mass production and can also contribute to cost reduction of fuel cell devices.
なお、上記実施例ではガスの流路〈３）を３本設けたも

You can expect it.
ところで上記実施例ではこの発明をリン酸型燃料電池に
適用する場合について説明したが、必ずしもこれに限定
されるものではない。By the way, in the above embodiment, the case where the present invention is applied to a phosphoric acid fuel cell has been described, but the present invention is not necessarily limited to this.
