Abstract:
1. A fuel cell for generating an electric energy with a chemical reaction between hydrogen and oxygen, comprising, a membrane electrode assembly for generating an electric field through the membrane electrode assembly with the chemical reaction between the oxygen and the hydrogen, a pair of first and second contact members, the first contact member contacting a first side surface of the membrane electrode assembly, and the second contact member contacting a second side surface of the membrane electrode assembly, and a pressing member for generating a pressing force for urging each of the first and second contact members toward corresponding one of the first and second side surfaces in a pressing direction wherein the first and second contact members contact each other through a mutual contact area other than the first and second side surfaces while the first and second contact members are mechanically connected to each other through the first and second side surfaces, and in a cross sectional view of the fuel cell taken along an imaginary plane which imaginary plane passes the pressing member and the first and second side surfaces and extends parallel to the pressing direction, the pressing member is arranged between the mutual contact area and each of the first and second side surfaces in a transverse direction perpendicular to the pressing direction.
