METHOD AND ARRANGEMENT FOR IMPROVED HEATING OF A HIGH TEMPERATURE FUEL CELL SYSTEM

摘要

The object of the invention is an arrangement for enhancing heating properties of a high temperature fuel cell device, each fuel cell (103) in the fuel cell device comprising an anode side (100), a cathode side (102), an electrolyte (104) between the anode side and the cathode side, and the arrangement comprises at least one heating source for heating the fuel cells (103) and means for determining essential temperature information of the fuel cells (103). The arrangement comprises means (122) to provide a part of the fuel cells (103) with voltage and current to facilitate an electrolysis mode of operation producing hydrogen, means (123) to simultaneously load another part of the fuel cells and means (109) for circulating fuel through the anode sides (100) of the fuel cells (103) to supply at least part of the hydrogen produced by the electrolysis to the fuel cells (103) being loaded.
