Fuel Cell Micro-grids describes an energy supply method based on a network of two or more proton exchange membrane fuel cells (PEM-FC). Such a network enables the effective use of exhaust heat, the simplification of the transmission network, the possibility of backup during disruptive hazards and the consideration of regional factors. Furthermore, green energy and renewable energy systems can be connected to the network, to function in cooperation with the fuel cells. For these reasons, it is believed that an increasing number of applications will make use of such fuel cell energy...
