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.
摘要翻译： 在根据本发明的燃料电池中，多个单电池各自包括阳极和阴极，每个阳极和阴极由多孔基底和介于阳极和阴极之间的电解质基质层形成。 在位于与电解质基体层相反的一侧的阳极的一个表面上形成燃料气体通道，在阳极的同一表面上形成电解质溶液渗透部。 单元电池堆叠在一起，并且在相邻的单元电池之间插入多个隔板元件以形成堆叠结构。 每个分离器元件在其表面上形成有位于面向阳极的一侧上的凹部。 凹槽用于储存电解质溶液并容纳电解质溶液渗透部分。 因此，如果电解质基质层被浸渍的电解质溶液被还原，则储存在凹槽中的溶液渗入基质层，流过可渗透部分。 结果，能够防止燃料电池的电压下降，能够延长燃料电池的连续运转。
