Abstract
A fuel cell stack has stacked individual fuel cells, each of the fuel cells having a cell frame, and an anode separator and a cathode separator disposed on respective sides of the cell frame, in which an electrolyte membrane joined with an anode side gas diffusion layer and a cathode side gas diffusion layer on respective sides thereof is disposed in the cell frame, an anode side load bearing member that bonds and fixes the anode separator, the cell frame, and the gas diffusion layer to each other, so as to receive a compressive load acting in a stacking direction of the fuel cell, and a cathode side load bearing member that bonds and fixes the cathode separator, the cell frame, and the gas diffusion layer to each other so as to receive a compressive load acting in the stacking direction of the fuel cell.
