METHOD FOR REGULATING OPERATION OF FUEL CELL INSTALLATIONS CONTROLLED ACCORDING TO HEAT AND/OR POWER REQUIREMENT

摘要

The invention relates to a method for regulating the heat production of fuel cells in an operating mode which is controlled according to heat and/or power requirements. The invention is characterised in that with a constant or varying cell current, the anode gas stream of the fuel cell is regulated as a correcting variable through the forward or backward temperature of the heat circuit as a controlling variable, or controlled according to a set of characteristics. According to the invention, this enables adjustment to a constant forward temperature with changing heat reduction, as well as extensive separation of heat and electricity production.
