Fuel cell assembly and method for manufacturing the same

A fuel cell assembly comprising:

• an electrode member that has a membrane electrode assembly having an electrolyte membrane and an electrode catalyst layer, and a gas diffusion layer disposed on at least one surface of both surfaces of the membrane electrode assembly in a thickness direction;
• a solid rubber gasket that, having a direction intersecting a stacking direction of the electrode member as a surface direction, is disposed in a frame shape on an outward side of the electrode member in the surface direction;
• and
• a bonding member that has a thermoplastic polymer, is disposed separately from the gasket in a frame shape on the outward side of the electrode member in the surface direction, is bonded to the electrode member and the gasket, and integrates the electrode member and the gasket,
• wherein a form of bonding the bonding member to the electrode member is at least one of impregnation with the gas diffusion layer and bonding to the membrane electrode assembly,
• wherein at least an outer circumferential end surface of the electrolyte membrane is coated with the bonding member, and
• wherein in the stacking direction of the electrode member, a thickness of the bonding member is equal to or larger than a thickness of the gas diffusion layer disposed on the one surface of the membrane electrode assembly, and at least a portion on a surface of the bonding member intersecting the thickness direction is coated with the gasket.
