Quant F – Flow Cell Sports Car on Display at Geneva Motor Show

Annika Tostengard — Tue, 13 Oct 2015 16:58:46 +0000

This year at the Geneva Motor Show, an exciting new technological wonder was on display: a sports car that runs off “flow cell” technology. The Quant F, as it’s called, from carmaker Nunzio La Vecchia, gets 746 kW (1,000 hp) of energy and can travel 500 m (805 km). The sports car was actually around […]

In order for the anode and cathodes in hydrogen fuel cells to survive, that is, do the job without degrading, they are covered with a material that needs to resist corrosion as well as conduct electricity. Unfortunately, some of the materials needed for such coatings, such as platinum, are expensive. Additionally, the processes used are […]

A new magnesium fuel cell using saltwater as electrolyte is now being commercialized by Tokyo-based Furukawa Battery, a company specialized in power systems. The electrolyte, just like in any other fuel cell, carries charged particles from one electrode to another, and electricity is generated following this reaction. “It is now possible to install an inexpensive […]

Reducing Platinum and Adding Gold: Three Inventions That Increase Fuel Cell Efficiency and Decrease Price

Ovidiu Sandru — Thu, 20 May 2010 19:05:05 +0000

Fuel cells are indispensable for hydrogen powered cars, and it looks like hydrogen may be the ultimate energy storage that meets all the demands of a clean "fuel" (though it's only a carrier, not a fuel). Fuel cells, are expensive, though, and their price is due to platinum, which is a rare metal.

Dealloying Process Creates More Efficient and Cheaper Platinum for Fuel Cells

Ovidiu Sandru — Wed, 28 Apr 2010 09:20:46 +0000

Fuel cells are usually expensive because they use platinum as a catalyst. To make them more appealing to the market, researchers from the DOE's National Accelerator Laboratory and the University of Houston, have created a new type of platinum catalyst, reducing the use of the pure metal down to 80 or even 70 percent, thus reducing the overall cost.

63% Efficient Solid Oxide Fuel Cell Developed by NGK

Ovidiu Sandru — Thu, 18 Jun 2009 05:03:41 +0000

Highly efficient hydrogen fuel cells are wanted due to the high price the existing ones have so far. So, being efficient means less money spent on them, and more market share for hydrogen. SOFCs (solid oxide fuel cell) are a type of hydrogen fuel cell that use solid (not liquid) electrolyte to do their job, while being much more efficient.

New Membrane by Chinese Scientist Can Make Fuel Cells Cheaper

Ovidiu Sandru — Thu, 18 Dec 2008 04:20:07 +0000

Currently, platinum is used as a catalyst in hydrogen fuel cells, making them so expensive and hence unappetizing to customers. Lin Zhang, a Chinese scientist, has discovered a membrane that could make the usage of platinum history, and make fuel cells cheaper than ever.
