Abstract

To prevent the dehydration of a fuel cell membrane, the air flow and in some cases also the hydrogen flow humidity are adjusted by the injection of water. Obtaining suitable fuel cell membrane humidification is a challenge when searching for optimal fuel cell performance. Respective operational humidity of the anode and cathode streams having dew points close to the fuel cell operating temperature is required. Also, the load and immediate surroundings are constantly changing, and, so the membrane humidity needs to respond to the transient state accordingly. A quasistatic model of the water circuit of a typical cell system is developed and used.
