ABSTRACT:
In order to provide a fuel cell stack which can sufficiently use a current range that can originally be output by a fuel cell unit, and from which high output can be obtained even with a small size, a thickness of an oxygen flow field plate is made large for a fuel cell unit having a relatively high temperature during operation, and the thickness of the oxygen flow field plate is made small for a fuel cell unit having a relatively low temperature during operation.
