Design and experimental verification of a fuel cell/supercapacitor passive configuration for a light vehicle

The fuel cell/supercapacitor passive configuration without using any DC/DC converters is promising in automotive applications as it can downsize the cell stack, maintain peak power capability, improve system efficiency, and remove need of additional control. This paper presents design characterization a hybrid for 60 V light vehicle. A detailed procedure test platform presented with each component modelled experimentally verified. voltage error supercapacitor model steady state within 2% 3%, respectively. Experimental results also validate function under conditions step load drive cycle. simulation matches measurements when current applied. provides transient due to its smaller resistance while handles current, which makes possible stack. For cycle examined this paper, stack be downsized one third power.
