FUEL CELL STACK

摘要

A fuel cell stack includes fuel cells, first and second rectangular end plates, and side panels. The fuel cells are stacked in a stacking direction to form a stacked fuel cells having a first end and a second end opposite to the first end in the stacking direction. The side panels are disposed between and fixed to the first and second rectangular end plates to surround the stacked fuel cells. The side panels include a first side panel and a second side panel opposite to the first side panel. The first side panel and the second side panel each have an asymmetric shape and are disposed so as to be point-symmetric to each other with respect to a fuel-cell central axis extending in the stacking direction and passing through a center of the fuel cells.

主权项

1. A fuel cell stack comprising:
a plurality of fuel cells that are stacked, each of the fuel cells generating electric power by an electrochemical reaction between a fuel gas and an oxidant gas; a pair of rectangular end plates disposed at both ends in a stacking direction of the fuel cells; and side panels disposed between the pair of end plates and fixed to respective sides of the end plates, wherein the side panels include a first side panel and a second side panel that are disposed at opposite positions, and wherein the first side panel and the second side panel each have an asymmetric shape and are disposed so as to be point-symmetric to each other about a fuel-cell central axis extending in the stacking direction.
