Abstract
A fuel cell separator is pressed so that one side thereof defines a gas flow channel and that the other side thereof defines a coolant flow channel. A width dG and a cross-sectional area SG of the gas flow channel and a width dW and a cross-sectional area Sw of the coolant flow channel satisfy a relationship: dG≧dW or a relationship: SG≧SW.
