Embodiment Construction

[0019] Figure 4A schematic diagram of a fuel cell system 10 of the invention according to a first embodiment of the invention is shown. The fuel cell system 10 includes a fuel cell stack 14 having any number of fuel cells. However, the fuel cell system 10 can also include a single fuel cell. The fuel cell stack 14 is connected at its anode inlet end to a reformer 24 for providing hydrogen-rich reformate to the fuel cell stack 14 at the anode inlet end of the fuel cell stack 14 . To this end, the recombiner 24 is connected at its inlet end to a fuel supply 26 and to an air supply 28 . Deliver fuel and air to the inlet port of reformer 24 by fuel supply device 26 and air supply device 28, delivered fuel and air can form the mixture of fuel / air in reformer 24 and can be in the work of reformer 24 transformed into recombinants. In addition, the fuel cell stack 14 is connected at its anode outlet to an afterburner 16 , to which recombines with a reduced hydrogen content produc...

Abstract

The invention relates to a fuel cell system (10) with a first heat exchanger (12), via which cathode inlet air can be supplied to a fuel cell or a fuel cell stack (14) and to which a mixture of afterburner exhaust gas from an afterburner (16) and cathode exhaust air produced in the fuel cell or the fuel cell stack (14) can be supplied in order to enable heat exchange between the cathode inlet air and the mixture by means of the first heat exchanger (12). The invention provides that a second heat exchanger (18) is provided, via which the cathode inlet air can be supplied by the first heat exchanger to the fuel cell or the fuel cell stack (14) and via which the afterburner exhaust gas can be supplied to the first heat exchanger (12) so as to form the mixture, in order to enable heat exchange between the afterburner exhaust gas and the cathode inlet air by means of the second heat exchanger (18).

Description

technical field [0001] The invention relates to a fuel cell system with a first heat transfer device, through which the cathode air can be fed to the fuel cell or the fuel cell stack, and the exhaust gas of the after-burner and the fuel The mixture composed of cathode exhaust gas produced in the battery or fuel cell stack can be fed to the first heat transfer device, so as to realize the heat transfer between the cathode air and the mixture. Background technique [0002] Fuel cell systems with heat exchangers or heat exchangers for cathode air preheating are generally known in the prior art. exist figure 1 An example of such a fuel cell system is shown in . The fuel cell system 10' includes a fuel cell stack 14'. The fuel cell stack 14' is connected at its anode inlet end to a reformer 24' so that hydrogen-rich reformate can be delivered from the reformer 24' to the anode end of the fuel cell stack 14'. For the production of reformate, the recombiner 24' is connected to ...
