FUEL CELL STACK AND LOAD DISTRIBUTION METHOD INVOLVING USE OF FUEL CELL STACK

摘要

A fuel cell stack includes: an anode side load bearing member (30) that fixes an anode separator (25A), a cell frame (21) and a gas diffusion layer (24) to each other to receive a compressive load acting in the stacking direction of individual fuel cells (20); and a cathode side load bearing member 40 that fixes a cathode separator (25B), the cell frame (21) and a gas diffusion layer (26) to each other to receive a compressive load acting in the stacking direction ± of the fuel cells (20), wherein a load canceling member (50) to cancel a tensile load acting in the stacking direction (±) of the fuel cells (20) is provided in the anode side load bearing member (30) or the cathode side load bearing member (40) or both of the anode side load bearing member (30) and the cathode side load bearing member (40).
