Abstract
【課題】 燃料電池の部材点数を削減し、製造工程を短縮することができるセパレータを提供することである。
【解決手段】 セパレータ1は、水素ガスおよび酸素ガスの流路を分離する分離部13と、外周部に設けられ、水素ガスおよび酸素ガスの漏出を防ぐシール部とを有している。分離部13とシール部14とは、金属薄板を塑性変形加工、たとえばプレス加工することによって一体形成する。さらに耐熱性を向上させるために、プレス加工後に、BH
(Baked Hardening)処理を施したものが好ましい。
【選択図】 図2
Description
最もよく使用されているものとして緻密性カーボンがある。緻密性カーボンは導電性、耐食性に優れ、機械的強度も高い。また加工性がよく軽量である。しかし、振動や衝撃に弱く、切削加工が必要なため、加工費が高くなる。また気体の不浸透化処理を施す必要がある。
燃料ガスおよび酸化剤ガスの流路を分離する分離部と、
外周部に設けられ、燃料ガスおよび酸化剤ガスの漏出を防ぐシール部とを有し、
分離部とシール部とは塑性変形加工によって一体形成されることを特徴とするセパレータである。
また本発明は、分離部には、電解質組立体の触媒電極形成面に平行で、互いに平行な複数の凹形状の流路溝が形成されることを特徴とする。
Assembly)とも呼ばれる。
第1および第4の実施形態については、セパレータ1は、金属薄板30からなるので、プレス加工によって分離部13とシール部14とを一体形成する。具体的には、ビーディング加工により外周部にシール突部を形成するとともに、エンボス加工により中央部に流路溝を形成する。
