63% More Efficient Solid Oxide Fuel Cell
17 June 2009 | Green Technology | 1 Comment
SOFC (solid oxide fuel cell) is a new type of fuel cell developed by NGK Insulators, and it uses hydrogen gas as fuel.Researchers have found through experiments that this new fuel cell achived a LHV(lower heating value) of 63%.The output power produced by using this fuel cell is 700W at an operating temperature of 800 Celsius degrees.An important advantage of this 1,5 mm cell is that cause, can be stacked together, so the output power will be sevral times increased.
“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.The company provided a stack in which tens of the cells are layered to a leading oil company in Japan, asking it to evaluate the fuel cell’s power generation performance. And it will aim to commercialize the cell for use in homes and commercial facilities such as convenience stores and shopping malls by further improving its performance. The company is planning to advance the development through technical alliances and joint developments with other companies.” -Techon

Hydrogen was all the hype in the 90′s. Where are they now….lol
