GM expanding into new commercial applications for its HYDROTEC fuel cell systems

Green Car Congress

These fuel cell generators could ultimately replace gas- and diesel-burning generators with fewer emissions at worksites, buildings, movie sets, data centers, outdoor concerts and festivals. This prototype is equivalent in size to a 60-kW generator and produces nearly 70% more power than traditional diesel generators.

Swedish Energy Agency grants PowerCell $1.4M loan for the development of next-generation fuel cell APU system

Green Car Congress

PowerCell selected an Auto Thermal Reactor (ATR) technology to evaporate (not combust) the diesel and extract hydrogen-rich gas with gas purity well within the limits of what a low temperature PEM fuel cell can support in terms of CO. The reformer module is combined with the fuel cell module by balancing the heat and water in the system.
