Abstract
A porous body for a fuel cell is interposed between a membrane-electrode assembly (MEA) and a bipolar plate to form a gas channel through which a reactant gas flows in a predetermined direction, the porous body including: a main body disposed to contact the bipolar plate; and a plurality of ribs each including a land portion disposed to contact the MEA and a connecting portion connecting the land portion to the main body, in which an area of the land portion is gradually narrowed from an upstream part to a downstream part of the gas channel.
