Ammonia Fueled Fuel Cell Vehicle:The New Concept of a Hydrogen Supply System
SAE Technical Paper Series, 2004<div class="htmlview paragraph">Ammonia has a potential as a liquid fuel for fuel cell vehicles, because it can be easily liquefied at a lower pressure and theoretically dissociated to the mixture of high-content hydrogen and nitrogen. Ammonia also has an advantage in terms of global warming because of carbon-free fuel. A fuel cell vehicle system

A fuel cell uninterruptible power supply (FC-UPS) system
2013 5th International Conference on Power Electronics Systems and Applications(PESA), 2013The architecture of the UPS based on PEM Fuel Cell (PEMFC) is investigated. Firstly, the output characteristics of PEMFC are studied. High efficiency power conversion from hydrogen energy to electric power is emphasized. The characteristics match between PEMFC and load is another key issue.
