固体高分子電解質型燃料電池

Solid high polymer electrolyte fuel cell

Abstract

(57)【要約】 【目的】低温の加圧板中を通過する過程においても反応 ガスに水滴の発生を生じることの無い固体高分子電解質 型燃料電池を提供する。 【構成】加熱装置5は、銅材を用いて加圧板2の本体部 とほぼ同一の厚さ寸法を持つ円筒状の外形と,その内部 に円筒状の空洞部291を持ち,固体高分子電解質型燃 料電池(スタック)が備える加圧板2の本体部に装着さ れる加熱部51と、空洞部291を内側から気密に塞ぐ と共に,中心部に酸化剤ガス98を通流させる貫通穴2 92aが形成されている銅材製のガス通流部292とで 構成されている。空洞部291には、電気絶縁板4が備 える熱媒99を通流させる通流路41を介して、スタッ クが備える単位燃料電池の積層体を冷却することでその 温度が上昇された熱媒99が供給される。
PROBLEM TO BE SOLVED: To provide a solid high polymer electrolyte fuel cell by which a waterdrop is not generated in reaction gas even in a process of passing through into a low temperature pressurizing plate. SOLUTION: A heating system 5 is composed of a heating part 51 which has a cylindrical external shape which uses a copper material and has almost the same thickness dimension as a main body part of a pressurizing plate 2 and a cylindrical cavity part 291 inside of it and is installed in the main body part of the pressurizing plate 2 provided in a solid high polymer electrolyte fuel cell (a stack) and a copper material-made gas flowing part 292 which airtightly blocks up the cavity part 291 from inside and in which a through hole 292a to flow oxidizing agent gas 98 is formed in a central part. A heating medium 99 whose temperature is raised by cooling a laminated body of a unit fuel cell provided in the stack, is supplied to the cavity part 291 through a flowing passage 41 to flow the heating medium 99 provided in an electric insulating plate 4.
