摘要
The cell unit has a membrane/electrode assembly including two electrodes (Ai, Bi) that are separated by a proton-exchange membrane (Mi). Gas diffusion layers (GDL-Ai, GDL-Bi) are stacked on respective assembly surfaces between the electrode assembly and a current collector plate (Pi), and exhibit different rigidity. One of the gas diffusion layers exhibits greater Young modulus with respect to pressure applied along thickness than Young modulus of the other layer in a ratio about minimum of 100.
