In a fuel cell comprising a laminate wherein a membrane electrode assembly is held by separators, the separator (20A) has a projection (21) contacting an membrane electrode assembly (10) with the contact angle between this projection (21) and the membrane electrode assembly (10) is set smaller than the contact angle of water with respect to the surface of the separator (20A). Regardless of the surface property of the separator, a corner part formed between the separator projection and membrane electrode assembly which contact with each other is so structured that water is unlikely to remain or penetrate. Thus, the draining capability of the gas channel is enhanced, improving power generating performance.
