Description of the Related Art Polymer solid oxide fuel cells are attracting attention as a power source for electric vehicles and spacecraft because they are compact and can obtain a high current density as compared with phosphoric acid fuel cells. Also in the development of this field, various electrode structures, catalyst production methods, system configurations, etc. have been proposed. By the way, it is considered that when trying to extract a high current density, the rate of mass transport to the surface of the catalyst electrode becomes rate-determining.In particular, in order to make the mass transport inside the catalyst electrode smooth, the reaction gas smoothly flows into both the cathode and anode sides and It is necessary that the water vapor generated on the cathode side be discharged outside the system so as not to hinder the inflow of oxygen.

As shown in FIG. 5, the cathode current collector A / cathode B / polymer solid electrolyte (ion exchange membrane) C / anode D / anode current collector E has a five-layer sandwich structure. In order to facilitate mass transport in this structure, attempts have been made to minimize the amount of catalytic metal supported on the cathode and anode, and to thin the electrode layers on the cathode and anode using a high-concentration catalyst. .. However, if the electrode layer is made thin, the material transport will be good, but the catalytic reaction at the electrode will be rate-limiting, that is, the improvement of the material transport and the increase in the reaction amount of the catalyst electrode are contradictory, and there is a problem that both cannot be satisfied. there were.

る。The details of the present invention will be described below. As described above, in the conventional 5-layer sandwich structure, since the cathode current collector and the anode current collector are not porous, there is a clear boundary between the current collector and the anode or the cathode, and Even if the body and the anode or the cathode are pressure-bonded by hot pressing or the like, the depth of penetration of the anode particles or the cathode particles into the current collector is about 0 to 5 μm. On the other hand, in the present invention, the current collector is made porous, and the anode and the cathode are pressure-bonded to the current collector for the anode and the current collector for the cathode, respectively. The electrode catalyst is configured to penetrate deeply into the inside of the current collector. The electrode particles may exist over the entire thickness of the current collector, or may exist only on the boundary side between the current collector and the anode or the cathode. The thickness is usually 10 to several hundreds of μm, depending on the thickness of the body. This thickness can be adjusted by the porosity of the current collector and the amount of solvent during the production of the current collector and electrode particles by pressing. The higher the porosity and the higher the amount of solvent remaining, the more the electrode particles penetrate. The degree increases.

る。According to this structure, the distance that the gas moves from the opposite surface of the collector to which the reaction gas is supplied to the electrode particles that form the anode and the cathode is reduced to improve the mass transport, that is, the reaction gas. It becomes possible to smoothly perform the inflow of water and the discharge of water vapor. Moreover, since the substance transport can be improved without reducing the amount of the electrode particles, the substance transport can be improved while maintaining the reaction amount, and the above-mentioned problems of the prior art can be solved. The current collector in the fuel cell of the present invention is not particularly limited as long as it is porous, but carbon paper, a sintered sheet of metal particles, carbon, a metal mesh or the like can be preferably used.

い。Further, as the electrode particles constituting the anode and the cathode, the conventional particles in which carbon powder is supported by a catalytic metal such as platinum may be used as they are. The electrode particles do not have to have a catalyst supported on all of them, and may be a mixture of catalyst-supported particles and unsupported particles. Furthermore, it is desirable to coat the electrode catalyst particles with an ion exchange resin to improve the affinity with the ion exchange membrane. As the ion exchange membrane for partitioning the anode and the cathode, the one used in the conventional fuel cell may be used as it is. For example, perfluorocarbon sulfonic acid type ion exchange membrane (trade name Nafion)
Alternatively, it is preferable to use a carboxylic acid type ion exchange membrane.

The generated water vapor can be easily released to the outside of the system, and mass transport is greatly improved. Then, by coating the cathode particles 2 and the anode particles 6 with an ion-exchange resin, active points of catalytic reaction and ionic conductivity can be obtained.
