Abstract

See full text

A fuel-cell unit cell comprises an MEGA plate with a resin frame, and two separators. There is formed a gas manifold hole in an outer edge portion of the resin frame. There is provided a gas-flow-path forming portion with a recessed-and-protruded shape on the first surface of the resin frame for forming gas flow paths between the gas manifold hole and the first surface of the MEGA. There is also formed a fusion-bonding portion for surrounding a periphery of the gas manifold hole to cut off gas circulation between the gas manifold hole and the second surface of the MEGA and for bonding the resin frame and the second separator with each other, on the second surface of the resin frame so as to pass across a backside of the gas-flow-path forming portion. The fusion-bonding portion is formed from a first resin, and the gas-flow-path forming portion is formed from a second resin higher in melting point than the first resin.
