Abstract
A method is disclosed for manufacturing a fuel cell that includes a membrane electrode assembly, a sealing frame surrounding the membrane electrode assembly, and bipolar plates. The method includes (i) placing a prepared membrane electrode assembly into a pre-designed mold, (ii) injecting a sealing material composed of a first component and a second component into the mold and cooling it to solidify thereby forming the sealing frame, wherein the sealing frame has an inner peripheral region and an outer peripheral region, and wherein the first component in the inner peripheral region has a first proportion different from a second proportion of the second component in the outer peripheral region, and (iii) assembling the bipolar plates on both sides of the membrane electrode assembly and the sealing frame. Also disclosed is a corresponding fuel cell which enables cost-effective and rapid mass production while improving moldability and mechanical strength.
