Slide bearing for cooling water circulation pump in fuel cell |
摘要 |
A slide bearing is proposed which rotatably supports a rotary shaft of an impeller in a cooling water circulation pump mounted to a fuel cell. The slide bearing is formed of a synthetic resin containing no metal ions such as polyetherketone resin. This prevents impurities originating from the slide bearing from being dissolved into cooling water for the fuel cell.
