Fuel Cell for Staionary Facility
Stationary fuel cells which provide electricity (and sometimes heat) but are not designed to be moved. These include combined heat and power (CHP), uninterruptible power systems (UPS) and primary power units.
CHP units are sized between 0.5 kWe and 10 kWe, use either PEM or SOFC technology and take advantage of the fact fuel cells generate heat alongside electricity. By making use of this heat, for example to make hot water, the overall efficiency of the system increases. Fuel cells are also more efficient at generating electricity which gives CHP units overall efficiencies of 80-95%. Residential CHP units have been deployed extensively in Japan with more than 10,000 cumulative units by the end of 2010 providing home power and heating. South Korea has also deployed CHP units for residential use but, as in Japan, their purchase still relies upon government subsidies.
