Flexible fuel cell

ITM Power, the UK fuel cell developer, says that it has successfully produced a 20W fuel cell stack that has potential for both military and civilian use.



This device, constructed using ITM’s patented materials and production process, operated successfully over a three day period producing in excess of 20W.



But, the company adds, the materials, ionomer and electrode/catalyst have been tested using the same fuels for periods exceeding 200 hours without significant degradation.



The present device operates using two liquids, a liquid fuel and a liquid oxidant. Using two liquids enables the device to operate at high altitudes, such as in an aircraft, in polluted environments as well as underwater.



However, the company has the ability to develop cells that can use other fuels if required.
