Abstract
Idling stop is important to reduce exhaust gas from vehicles for preventing environmental problems such as global warming. Especially, diesel powered trucks discharge harmful gases such as CO_2, Nox and PM. However, refrigerator vehicles used to transport the frozen food cannot do idling stop. A DME fuel-cell hybrid system is an improvement moving system to reduce emissions. The miniaturization becomes the problem for achieving this system and it is important to realize high efficiency reforming. This of efficiencies of reforming with or without Li_4SiO_4.
