Manufacturing method of a fuel cell module

A cross leakage and external leakage of the gas, a shortcut is provided while preventing a simple structure without using a complicated seal structure, downsizing, the battery module and the battery stack of the fuel cell can realize a reduction in thickness . An electrode - and the membrane assembly, the separator, and integrally bonded together by resin containing fibers at least partially, the electrode - at least part of the gas diffusion layer provided in contact with the membrane assembly provided so as to impregnate the resin. .FIELD 1
