Abstract
A fuel cell includes: an electrolyte membrane; a first reactive gas channel that is provided on a first surface side of the electrolyte membrane; a second reactive gas channel that is provided on a second surface side of the electrolyte membrane; and a coolant channel. The coolant channel is configured such that a flow direction of the first reactive gas flowing in the first reactive gas channel is opposite to a flow direction of the second reactive gas flowing in the second reactive gas channel, and a downstream portion of the flow of at least one of the first and second reactive gases, in a plane of the electrolyte membrane, is cooled from the central portion within the plane.
