Abstract
A fuel cell stack includes a first end power generation unit and a first dummy unit adjacent to a power generation unit at one end of a stack body in a stacking direction. In the first end power generation unit, a first separator is stacked on the power generation unit, a first membrane electrode assembly is stacked on the first separator, a second separator is stacked on the first membrane electrode assembly, an electrically conductive plate is stacked on the second separator, and a third separator is stacked on the electrically conductive plate. A coolant is supplied to a coolant flow field formed between the power generation unit and the first end power generation unit, for cooling a second membrane electrolyte assembly of the power generation unit and the first membrane electrode assembly of the first end power generation unit.
