PURPOSE:To make even the lifetime serviceable and improve the battery characteristics by changing the electrolyte retaining amount of reservoir plate in compliance with the temp. difference unit cell to cell. CONSTITUTION:A fuel cell concerned consists in a layer of unit cells 22, which are equipped with reservoir plate for holding an electrolyte, and separator plates in such a structure that cooling plates 3 to control the operating temp. are laid between blocks while a plurality of unit cells are grouped as one block 25, wherein the thickness of the reservoir plate of the intra-block unit cell is formed in different dimension in compliance with the temp. difference from unit cell to cell. That is, the thickness of the reservoir plate made smaller on the side with the low temp. part unit cells 22B, 22C layered in the position contacting the cooling plate 3 than the thickness of the high temp. part unit cell 22A layered in the center of the block 25. |
