Fuel Cell Stack
Nissan has just revealed its next-generation fuel cell stack, one that offers 2.5 times greater power density than the version the automaker created in 2005. Two-and-a-half times may not mean much to most readers, so how about this: Nissan says the fuel cell power density of 2.5 kW per liter is the "world's best" among automakers.
RE Hydrogen Ltd (REH) was awarded £25,000 ($39,285 U.S. at the current exchange rate) from the UK's Technology Strategy Board to scale up their prototype electrolyzers, which can produce hydrogen gas for use in the transportation industry. REH claims that its electrolyzser is one of the most efficient available and, perhaps more importantly, it's also said to be up to 93 percent cheaper than other electrolyzers on the market today. REH will use its award money to build a prototype 5 kW sta
While improvements to the tried-and-true internal combustion engine continue to come in small, incremental bits year after year, hydrogen fuel cell technology is progressing in leaps and bounds. Evidence of such can be seen in the latest version of General Motors' hydrogen fuel cell system.
