Abstract
A fuel cell metal separator structure includes a first separator in contact with a first membrane electrode assembly and a second separator in contact with a second membrane electrode assembly. In the stacking direction of the first separator and the second separator and the membrane electrode assemblies, in an reaction area formed between the two membrane electrode assemblies, an electrically conductive member is put between the first separator and the second separator, and in the sealing portion on a periphery of the membrane electrode assembly, the first separator and second separator are in direct contact with each other so that a space for sealing is expanded due to the increased depth of the sealing grooves.
