An Ammonia-powered Fuel Cell Electric Golf Cart System
Ammonia (NH3) is a carbon-free hydrogen (H2) carrier, which enables liquid-phase H2 storage and transport under mild conditions. Although the concept of NH3-to-H2 has been frequently proposed, the practical application of NH3 as the energy source for H2 power automotive systems is rarely reported. To close the gap between NH3 supply and H2 utilization, we demonstrated an NH3-powered fuel ...

Effect of reforming on the overall efficiency of a solid oxide fuel-cell based power plant system fed by methane
In the present work, energy and exergy system analysis are used to estimate the thermodynamic performance of a SOFC system fuelled by methane. More precisely, the present work examines in detail the influence of the presence or absence of the reformer within the whole apparatus and the consequent energy and exergy losses due to the reforming process. It was found that the exergetic efficiency for ...
