High Power Density Fuel Cells Test Update

 

ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to announce an early technical result from the initial phase of the high power density fuel cell membrane testing, an ambitious technology development project supported with GBP108,000 of research funding from the Carbon Trust.

 

ITM Power has demonstrated exceptionally high power densities by developing its proprietary hydrocarbon membrane materials for hydrogen/oxygen fuel cells. A step change from the current state of the art has been achieved, with what is believed to be the highest power density ever recorded for a PEM fuel cell (5.5W/cm2 and 10A/cm2) using pure oxygen. ITM Power has now successfully demonstrated the performance of the membrane in a hydrogen/air fuel cell developing over 2.1W/cm2 and 4A/cm2, more than doubling the power density performance presently available on the market.

 

While the Company's initial investigations focused on hydrogen and oxygen fed fuel cells, a commercial fuel cell system for deployment in a vehicle requires air to be used as the oxidant. This early result with air exceeds the ambitious target of 1.5W/cm2 which was defined as part of the Carbon Trust project and is further evidence of the potential for ITM Power's materials to offer a step change in performance.

----------------------------------

 

Major car manufacturers will be taking note for their hydrogen fuel cell cars of the future -- ITM's patented membrane has much lower cost and substantially higher performance.

Scientists have engineered a cheap, abundant alternative to the expensive platinum catalyst and coupled it with a light-absorbing electrode to make hydrogen fuel from sunlight and water.

 

The secret ingredient is molybdenum sulfide.

 

A team of researchers have engineered a cheap, abundant alternative to the expensive catalyst platinum and coupled it with a light-absorbing electrode to make hydrogen fuel from sunlight and water. The discovery was published in Nature Materials by theorist Jens Nørskov of the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University and a team of colleagues led by Ib Chorkendorff and Søren Dahl at the Technical University of Denmark. The team optimized a photo-electrochemical water splitting device by designing light absorbers made of silicon arranged in closely packed pillars, imaged above using a scanning electron microscope. After dotting the pillars with tiny clusters of the new catalyst and exposing the pillars to light, researchers watched as hydrogen gas bubbled up -- as quickly as if they'd used costly platinum.
