Abstract

A fuel cell is provided which includes iron-based alloys for the construction of the solid parts of the fuel cell. The fuel cell includes a membrane electrode unit and solid constructive parts which may include current collectors, a cell frame and a bipolar plate. At least one of these solid constructive parts is made from an iron-based material that preferably has an effective weight percent of iron of greater than or equal to 26.9 percent.
