Fuel cell system and method for time-controlled start-up / shut-down of a fuel cell system

摘要

Fuel cell system, comprising an auxiliary energy source which provides the auxiliary energy for starting up the fuel cell system and a switch by means of which the fuel cell system can be switched over from energy consumption from the auxiliary energy source to an energy output operation of a fuel cell block. Furthermore, a timing device controls the above switch, said switch or said timing device with an energy buffer, e.g. can be connected to a capacitor. After switching to an energy delivery mode, a temperature-controlled cooling device cools the fuel cell blocks. IMAGE
