The Characteristics of a PEM Fuel Cell Engine with 40 kW Vehicle Stacks

This paper describes a PEM Fuel Cell Engine (FCE) with 40 kW stacks designed for a car. This was developed by DICP and Sunrise Power and is funded by the Chinese “863” key project. The FCE system construction, stack performance, specifications, and operating characteristics are explained. The efficiency of the FCE is analyzed. The net power output for this FCE is 27 kW and the efficiency is 35–38%. The utilization of air and hydrogen are more than 50% and 97%, respectively.
