Fuel Cell Power SystemFeatures

Attention has been focused on fuel cells in clean power generation equipment that utilize liquefiedgas(LNG). The use of an electrochemical power generation method using hydrogen and oxygen in theair makes it extremely efficient and quiet. It is also very environmentally friendly, producing almost noNOx emissions when compared with combustion methods.
Effective utilization of gas by power generation
Reducing CO2 emissions by power generation used surplus gas
High-efficiency power generation under low load (Fig. 1)
Long life time (Overhaul every 7.5 years) (Other power generation method : every 2 - 3 years)
Clean exhaust gas (Fig. 2 and 3)
Low noise (Fig. 4)
