<P>PROBLEM TO BE SOLVED: To provide a fuel cell having a simple structure for improving the system efficiency successfully, while assuring to discharge the generated water from a reaction gas flow path. <P>SOLUTION: On a surface 14a faced with an electrolyte film/electrode structure of a primary carbon separator 14, an oxidizing agent gas flow path 30 is formed for communicating an oxidizing agent gas supply communication hole 18a with an oxidizing agent gas discharge communication hole 18b. The oxidizing agent gas flow path 30 has many linear flow path grooves 30a formed among many convex sections 32 extending in the direction of gravitational force. A tapering bent portion 32a is provided at the edge of the end on the outlet side of each convex section 32, while a protrusion 34 is provided as a baffle member for disturbing a flow of the oxidizing agent gas between the edges of the end on the outlet side of each convex section 32. <P>COPYRIGHT: (C)2008,JPO&INPIT |
