A team at the University of Delaware has demonstrated a direct ammonia fuel cell (DAFC) prototype with a peak power density of 135 mW cm -2 at 80 ?C. Together, these applications leave a substantial fraction of transportation energy usage dependent on chemical fuels. A paper on the work is published in the journal Joule. Zhao et al.
