Study of low-temperature-combustion diesel engines as an on-board reformer for intermediate temperature Solid Oxide Fuel Cell vehicles
Fuel cells have been recognized as a feasible alternative to current IC engines. A significant technical problem yet to be resolved is the on bound fuel supply before fuel cells can be practically used for vehicles. Use of an on-board fuel reformer can mitigate the fuel supply issue. In particular, …
