A test platform for automotive fuel cell systems was presented and some test results were reported. The test platform was developed based on a test bed of internal combustion engine with a dynamometer. the dynamometer acted as both the load and a measurement instrument. A fuel cell engine, a DC/DC converter and an induction traction drive motor with a DC/AC inverter were integrated to the system and were tested in the platform. Test results of one fuel cell system showed that the efficiency was 41 % (LHV) while 50 kW of electrical power was produced in the engine; the cell current density was 400 mA/cm2 when 0.65 V of average cell voltage was ontained in the stacks, the maximum mechanical power of the fuel cell system was 41 kW, and the best specific fuel consumption was 102 g/kWh. This test platform was feasible for evaluating all components of fuel vell systems, such as stacks, parasitic power engines, DC/DC converters and traction drive motors; and in this platform it was found to be convenient to uncover problems of electromagnetism compatibility in the fuel cell systems before being mounted into vehicles.
