Seal for fuel cell and forming method therefor |
摘要 |
A seal in a fuel cell for sealing a membrane electrode assembly comprises a pair of catalytic electrode layers, a polymerized electrolytic membrane held between the catalytic layers, and a gas diffusion layer layered on the outer surface of the catalytic electrode layer. The seal is integrally formed with the polymerized electrolytic membrane. The height thereof is greater than that of the gas diffusion layer. The difference between the heights of the polymerized electrolytic membrane and the gas diffusion layer is constant.
