PROBLEM TO BE SOLVED: To enhance the manufacturing efficiency of a fuel cell by efficiently conducting leak test. SOLUTION: In the manufacture of a fuel cell 10 having a built-in manifold, the specified number of separators and electrolyte membranes for constituting the fuel cell 10 are stacked on a lower block, an upper block is placed thereon, then they are fastened with nuts. By keeping this state for the specified time, adhesion of a fuel cell stack is completed. Inspection fluid such as nitrogen gas is supplied to a manifold within a fuel cell from an inspection fluid supply path installed in the lower block or the upper block, and a leak test is conducted. Therefore, after completion of connection of fuel cell stacks 100A-100D, since a leak test can be conducted in this state, efficiency of the leak test is enhanced and the manufacturing efficiency of the fuel cell can also be enhanced. |
