The present invention is intended to enable efficient assembly of a fuel cell stack without causing any damage to the conductive separator. In a fuel cell including an anode, a cathode, an electrolyte membrane interposed between the anode and the cathode, and conductive separators each having manifold aperturesand a flow channelfor supplying a gas to the anode or the cathode, manifold aperture connecting portionsare formed at an inlet-side end and an outlet-side end of the flow channel, respectively. Each of the manifold aperture connecting portionsis recessed below the upper surface of the conductive separator. Cover plates are fitted and fixed to the recessed portions, respectively.
