PURPOSE:To decrease contact resistance between an electrode and a collector electrode in a fuel cell. CONSTITUTION:A plurality of ribs 42 are formed in a collector electrode 40, and a flow path 48 of positive pole fuel is formed by this rib 42 and a surface of a positive pole 20. The positive pole 20 is formed by cutting a carbon cloth, plane woven by a warp 22 consisting of carbon fiber and by a weft 24 consisting of carbon fiber, so that a side of forming the periphery of the positive pole 20 is crossed at a 45 deg. angle respectively with the warp 22 and the weft 24. Consequently, each yarn of the warp 22 and the weft 24 of the positive pole 20 is crossed at a 45 deg. angle with the rib 20, and since the yarn comes into direct contact with the rib 42, in transmitting an electron to the positive pole 20 from the collector electrode 110, the electron is transmitted directly to each yarn from the rib 42. As a result, contact resistance between the collector electrode and the positive pole 20, generated by only contact resistance between the rib 42 and the yarn, can be decreased. |
