Surge avoidance and control of a centrifugal compressor in a fuel cell system

摘要: A fuel cell system is provided with an oxidant supply that utilizes a centrifugal compressor has surge control system. The provides recirculation port from the outlet back to inlet. valve in passage allows maintain its requested pressure and flow by selective reintroduction of compressed air inlet compressor. subjects higher mass rate where it can make more without surging, thereby returns “on map” situation.
