摘要: A fuel cell battery (2) has a structure in which a plurality of cells are stacked and in-series connected. The cells include a cell (15), and one or more cells (16) of a cell stack (11). Hydrogen that has entered the fuel cell battery (2) from a channel (12) is supplied to each cell through a supply manifold (13). After the amount of hydrogen needed for power generation is consumed, gas is discharged as a fuel off-gas into a discharge manifold (14), and then flows into the cell (15). This prevents impurities contained in the fuel off-gas from being accumulated in the cells (16), and causes the impurities to be accumulated in the cell (15). Thus, variations in the amount of power generation among the cells can be restrained in a fuel cell battery system that employs a dead-end method.

摘要: In a fuel cell stack, each separator is constructed by sequentially stacking and joining an anode-facing plate 42, a middle plate 43, and a cathode-facing plate 44. The anode-facing plate 42 has multiple hydrogen inlets 422i arranged in a two-dimensionally distributed manner on its plate surface. This arrangement effectively prevents a decrease of power generation capacity due to local accumulation of water produced in the course of electrochemical reaction for power generation or other impurities on the surface of either an anode or a cathode.
