| Abstract |
Influence of hydrogen fuel cell stack output current ripple caused by a one phase voltage-fed inverter system on efficiency of the fuel cell stack is investigated experimentally. The system includes hydrogen canister, 1.2 kW hydrogen fuel cell module, DC/DC step-up converter and PWM inverter. The system has two DC voltage stages: relatively low and variable voltage on the fuel cell output and stabilized high voltage on the input of the PWM inverter. The electrically isolated voltage-fed pushpull DC/DC step-up power converter with high frequency transformer is found as appropriate for this system from the conventional converters by the following criteria – high efficiency and high power density. |
