NGK Insulators Ltd. has developed a solid oxide fuel cell (SOFC) that uses hydrogen gas as fuel and achieved a lower heating value (LHV) of 63 percent, one of the highest in the world.
The SOFC features a power output of 700 watts and an operating temperature of 800°C.
The company lowered the resistance value by completely coating the cell's supporting anode with a thin film (5μm thick) of electrolyte (zirconia) and secured a sufficient power generation area by forming cathodes on both sides of the cell to achieve the large output, it said.
