Outperformance in fuel cell tests


AFC Energy, the industrial fuel cell power company, is pleased to provide an update on the latest trial of its 25 fuel cell cartridge undertaken at its Dunsfold industrial park facilities – which outperformed both the earlier trials.

A total performance improvement of 10.8% in electrical output was recorded, relative to the first 25 cell stack trial. This latest test represents a large stride forward in validation of AFC Energy’s KORE system technology as a prelude to commercialisation next year.

As context, a fuel cell requires a period of “warm up” from ambient temperature in order to achieve maximum operating performance. To date, AFC has accelerated this process by applying external heat sources to establish and maintain optimum fuel cell operating temperature. The ability to achieve the necessary levels of heat solely through fuel cell reactions in a relatively short period of time, as envisaged in the KORE system, will remove capital from the cost of the fuel cell system and improve the overall system efficiency (making it more affordable to produce and simpler to maintain and operate).

To date, AFC has successfully conducted three 25 fuel cell stack trials in 2014 using the same electrode configuration with the performance (voltage output). The performance of the second 25 cell stack trial (V3 CB 00070) was materially improved relative to the first (V3 CB 00067) by 6%.
