PROBLEM TO BE SOLVED: To enable an assembling work of fuel battery cells to be performed efficiently and excellently at a low cost.SOLUTION: A fuel cell 10 has a framed electrolyte membrane/electrode structure 26 which surrounds the outer periphery of an electrolyte membrane/electrode structure 26a and to which a frame-like insulating member 42 is connected, and a metallic separator 28. The metal separator 28 includes a first bipolar plate 46 and a second bipolar plate 48 that are joined to each other. The frame-like insulating member 42 is provided with a welded portion 45 which is welded to a first bipolar plate 46 by resistance welding.SELECTED DRAWING: Figure 3 |
