NOVELTY - A fuel cell module comprises electrode unit (2) having membrane electrode assembly (20) comprising electrolyte membrane (22) and pair of electrode catalyst layers (23a, 23b) that is disposed on both sides of electrolyte membrane in thickness direction, and having pair of porous layers (21a, 21b) disposed on both sides of membrane electrode assembly in thickness direction; and separator (3) disposed layered on electrode unit to contact porous layer(s). An adhesive rubber component (4) is disposed on peripheral edge portion of electrode member.    USE - A fuel cell module for proton-exchange membrane fuel cell used in power generation and as power source for automobiles.    ADVANTAGE - The fuel cell module can be easily manufactured, and can be extracted to enable inspection and repair. If failure occurs in module, it is easy to replace only the particular module. The peripheral edge portion of electrode unit is sealed by adhesive rubber component with high sealability, thus providing sealed regions having good durability. The adhesive rubber component has adhesiveness, so that there is no need to use separate adhesive agent. Due to the use of rubber, the amount by which porous layer is impregnated can be regulated, thus not requiring special treatment during molding. The rubber in which the pre-crosslinking composition is made to crosslink has low gas permeability, thus increasing sealability of adhesive rubber component. The use of organic peroxide allows crosslinking at lower temperature in shorter period, thus suppressing deterioration of electrolyte membrane due to heating during molding. The crosslinking agent is not prone to curing defects caused by impurities and contamination; and is resistant to effects of surrounding environment during operations and easy to handle. The adhesion force is not prone to decreasing even in operation environment of fuel cell. Good sealability can be secured even when fuel cell is operated for a long period, thus improving operation reliability of fuel cell. The fuel cell can be easily assembled by stacking fuel cell modules, thus improving productivity.
