Study on hot and cold starting characteristics of fuel cell system

摘要

In this paper, the starting characteristics of fuel cell system are studied firstly. The hot and cold starting characteristics of fuel cell system are measured by the starting time of fuel cell system, the energy consumption during the starting process and the hydrogen consumption during the starting process. Secondly, the cold and hot starting test of the fuel cell system is designed, and the experimental process is designed by using the orthogonal experimental method. 30kW, 60kW and 90kW fuel cell engines are selected for the test and the experimental data are recorded. Finally, the data obtained from the test are compared and analyzed comprehensively to show the relationship among the time, energy consumption and hydrogen consumption required to start the fuel cell engine at the same power and different temperature.
