MANUFACTURING METHOD FOR FUEL CELL

A manufacturing method for a fuel cell includes the steps of: (a) preparing a stack and separators in a pair arranged in such a manner as to hold the stack therebetween; (b) forming a separator-bonded stack by bonding the separators in a pair and a sealing part to each other; and (c) warping a membrane electrode assembly with the bonded sealing part in a gap by reducing the temperature of the separator-bonded stack to cause thermal shrinkage of the separators in a pair, thereby moving the sealing part with the bonded separators in a pair inward.
