Fuel cell stack

摘要

A fuel cell stack includes a first separator and a second separator, each separator having raised portions and channel portions on a first side and a second side, the channel portions on the first side being opposite the raised portions on the second side and the channel portions on the second side being opposite the raised portions on the first side. The stack also includes a membrane-electrode assembly located between the first separator and the second separator, and closely contacting the raised portions of the first side of the first separator and the raised portions of the second side of the second separator.
