Fuel cell and apparatus for producing fuel cell

A fuel cell formed by stacking membrane electrode assemblies and separators, the membrane electrode assemblies each including a pair of electrodes, and an electrolyte membrane interposed between the electrodes,

• wherein a resin frame member is formed integrally with an outer circumference of the membrane electrode assembly;
• in adjacent membrane electrode assemblies that sandwich the separators therebetween, a step is provided on an outer circumferential end of at least one of the resin frame members, which are adjacent to each other, such that the step is spaced from an outer circumferential end of the other of the resin frame members, and an adhesive layer is formed by filling, with an adhesive, a gap between the outer circumferential ends of the adjacent resin frame members;
• and
• the adhesive layer is provided to cover outer circumferential end surfaces of the resin frame members from the step.

An apparatus for producing a fuel cell formed by stacking membrane electrode assemblies and separators, the membrane electrode assemblies each including a pair of electrodes, and an electrolyte membrane interposed between the electrodes,

• the production apparatus comprising a first die member and a second die member;
• wherein, in a state in which two adhesion targets of the separators or the membrane electrode assemblies are stacked together, and an adhesive is provided as an adhesive layer at a step formed between the two adhesion targets, the first die member contacts one of the adhesion targets and the second die member contacts the other of the adhesion targets;
• and
• in a state in which the first die member and the second die member are closed together, a space is provided between outer circumferential end surfaces of the adhesion targets to form an end surface adhesive layer.
