Findings of the current development of hydrogen fuel cellsTomáš, MartinNovotný, Pavel
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...
There have accumulated enough experiences in revaluation of CO_2. (3) There is lack of hydrogen in present China and hydrogen price is quite expensive, but there exists great potentiality in hydrogen production. (4) The research and development of alternative automotive fuel has been active and ...
