Abstract

A fuel cell system including a fuel cell stack having an anode side and a cathode side, the anode side having an inlet for receiving fuel and an outlet for discharging anode exhaust gas, and the cathode side having an inlet for receiving oxidant gas and an outlet for discharging exhaust oxidant gas, and including a mixer/eductor for mixing the exhaust anode gas with the oxidant supply gas. The mixer/eductor is adapted to create divergent jets or streams of oxidant supply gas so as to enhance mixing and promote pressure loss reduction. Specifically, the mixer/eductor includes elements each disposed at an angle relative to the path of incoming oxidant supply gas which act to establish the multiple oxidant gas streams.
