    摘要: The invention provides an electrochemical power generator having a structure where a plurality of unit cells are stacked such that each pair of adjacent unit cells sandwich an interconnector therebetween. Each unit cell is formed such that an anode of a porous carbon substrate having an anode catalyst layer on one surface thereof and a cathode of a porous carbon fiber sheet having a cathode catalyst layer on one surface thereof sandwich a matrix layer containing an electrolyte solution of a concentrated acid solution therebetween so as to respectively bring the two surfaces of the matrix layer into tight contact with the anode and cathode catalyst layers. The interconnector is formed of a high density carbon plate. The electrochemical power generator uses as an anode reactant material a gas containing hydrogen as a major component, and uses as a cathode reactant material an oxidizing gas. The electrochemical power generator has excellent mechanical strength and may be efficiently and stably operated without deterioration over a long time. For this purpose, a plurality of grooves which function as a gas passage for the gas containing hydrogen as its major component are formed in the other surface of the anode, the cathode is thinner than the anode and is waterproofed, and a plurality of grooves which function as a gas passage for the oxidizing gas are formed in one surface of the interconnector.

    摘要: In a fuel cell according to the present invention, a plurality of unit cells each includes an anode and a cathode, each formed of a porous substrate, and an electrolyte matrix layer interposed between the anode and the cathode. A fuel gas channel is formed on one surface of the anode that is located on the side opposite to the electrolyte matrix layer, and an electrolyte-solution permeable portion is formed on the same surface of the anode. The unit cells are stacked in layers, and a plurality of separator elements are interposed between the adjacent unit cells to form a stacked structure. Each of the separator elements has a recess formed on its surface that is located on the side facing the anode. The recess serves to store an electrolyte solution and contain the electrolyte-solution permeable portion. Thus, if an electrolyte solution, with which the electrolyte matrix layer is impregnated, is reduced, the solution stored in the recess permeates the matrix layer, flowing through the permeable portion. As a result, the voltage of the fuel cell is prevented from dropping, thus permitting a prolonged continuous operation of the fuel cell.

First fuel gas passages, communicating with the first and third internal manifolds, are formed at the anode side of the separator element. Second fuel gas passages, communicating with the second and third internal manifolds, are formed at the anode side of the separator element. Thus, the fuel gas flows through the first internal manifold, the first fuel gas passages and the third internal manifold, and the fuel gas flows through the second internal manifold, the second fuel gas passages and the third internal manifold. As a result, the current density distribution and the temperature distribution are uniform.
