Title: FUEL CELL
Abstract:
In a fuel cell comprising a laminate wherein an electrode structure is sandwiched by separators, the separator (20A) has a projection (21) contacting an electrode structure (10) with the contact angle between this projection (21) and electrode structure (10) set smaller than the contact angle of water with the surface of the separator (20A). Regardless of the surface property of the separator, a corner part formed between the separator projection and electrode structure which contact each other is so constituted that water is hard to reside or penetrate. Thus, the draining capability of a gas channel is enhanced to improve power generating performance.
