Development of a high energy density power system using an ultra-light, open cathode fuel cell
1  Clean Energy Research Centre, Temasek Polytechnic


A 60W nominal power system using a low temperature proton exchange membrane fuel cell (LT-PEMFC) was developed and tested at the Clean Energy Research Centre of Temasek Polytechnic. The power system consists of an ultra-light, open cathode LT-PEMFC stack attached with low power fans as well as a fuel cell control board. The stack comprises of 15 cells with an estimated active area of 8cm2. The stack is designed to operate at a wide range of hydrogen pressure of 0.4bar to 2 bar gauge as opposed to industry standards of 0.3 to 0.6 bar gauge.  The stack is self-humidifying and is able to operate stably with dry hydrogen input. The stack is able to achieve 1W/g peak.
