<P>PROBLEM TO BE SOLVED: To effectively prevent each cell from generating a curve when forming one stack by pressurizing and laminating a plurality of power generation bodies (cells). <P>SOLUTION: Upon constituting a power generation body of a fuel battery, a raw material sheet wherein a water-soluble highly-rigid material 1 having rigidity higher than rigidity of a material forming a gas diffusion layer is scattered in a raw material sheet is used as a raw material sheet 2 for a gas diffusion layer used herein. The highly-rigid material prevents generation of the curve by removing a spring nature of the gas diffusion layer at the beginning. Power generation performance of the fuel battery is not blocked since the highly-rigid material disappears by dissolving into generated water after starting power generation. <P>COPYRIGHT: (C)2010,JPO&INPIT |
