Definitions
- the invention relates to a method for operating a Brennstoffzellenanordung according to the preamble of claim 1 and a fuel cell assembly itself, as indicated in the preamble of claim 6.
- the power density of a fuel cell assembly having stacked fuel cells is limited by, among other things, the possible cooling capacity, i. the amount of heat dissipatable from the fuel cell stack during its operation. As the power density increases, so does the amount of heat accumulating in each fuel cell, and if it can no longer be sufficiently dissipated, a further increase in power density is no longer possible.
- the possible cooling capacity i. the amount of heat dissipatable from the fuel cell stack during its operation.
- a process for the autothermal reforming of fuel containing higher hydrocarbons by means of catalytic steam reforming is furthermore also described in EP 0 989 094 A2.
- the fuel containing the hydrocarbons is first passed through a reactor containing the catalyst, where in the presence of water vapor, the higher hydrocarbons are removed or reduced, and then forwarded to an autothermal reformer, then from there resulting, rich in hydrogen and carbon monoxide product gas is deducted.
- JP6325783 describes the internal reforming in a molten carbonate fuel cell system, wherein a preformer formed as a heat exchanger is provided in which heat exchange between the fuel cell exhaust gas and a hydrocarbon having a carbon number of two or higher, that is, heat is transferred from the fuel cell Exhaust gas to the supplied fuel gas, a steam reforming reaction takes place.
- hydrocarbons such as butane or other light hydrocarbons can be used as fuel gas, in which the volume of the reformed gas is significantly greater than in the reforming of methane.
- the object of the invention is to provide an improved method of operating a fuel cell assembly in which the fuel cells with a higher power density can be operated. Furthermore, a fuel cell assembly is to be created, in which the fuel cells can be operated with a higher power density.
- the task is performed by a

- a fuel gas is partially converted to hydrogen in the first reforming units in thermal contact with the fuel cells in an endothermic reaction by absorbing heat from the fuel cells and the anodes the fuel cell is supplied.
- the endothermic reaction taking place in the first reforming units contains the reactions
- the exothermic back reaction occurring in the second reforming unit contains the reaction
- the setting of the reverse reaction in the second reforming unit is carried out by adjusting the temperature by the strength of the cooling.
- Fuel cell assembly provided with arranged in a stack of fuel cells and with the fuel cells in thermal contact first reforming units, wherein fuel gas in the first reforming units in an endothermic reaction with absorption of heat from the fuel cells partially converted into hydrogen and the anodes of the fuel cell is supplied.
- the first reforming units are provided to produce more hydrogen than in the fuel cell feasible, and that a coolable second reforming unit is provided, wherein a portion of the hydrogen-containing reformed fuel gas withdrawn from the first reforming units and the second reforming unit wherein the hydrogen contained in the supplied reformed fuel gas is subjected to an exothermic back-reaction in the second reforming unit, and the heat released thereby is dissipated by cooling the second reforming unit.
- the second reforming unit is a pre-reformer for receiving the fuel gas withdrawn from the first reforming units together with freshly supplied fuel gas from the outside.
- a conveying device for returning the fuel gas withdrawn from the first reforming units to the second reforming unit is provided.
- the delivery means provided for returning the fuel gas withdrawn from the first reforming units to the second reforming unit may be a pump or a side channel compressor.
- the second reforming means is provided for adjusting the backreaction by adjusting the temperature by the amount of cooling.
- the figure shows a schematic block diagram of an embodiment of the invention.
- a fuel cell arrangement shown in the figure contains in a stack 1 arranged fuel cells 2, of which in the figure in a schematic way only one is shown and which is used for generating elekticianm current from an externally supplied fuel gas, as shown in the drawing by the arrow, and an oxidizing gas, the supply of which is not shown in the figure.
- Internal, first reforming units 4 are provided with the fuel cells 2 in thermal contact, of which only one is shown in a schematized manner in the figure.
- fuel gas is partially converted into hydrogen in an endothermic reaction by absorbing heat from the fuel cells 2 and then supplied to the anodes of the fuel cells 2.
- the fuel gas is supplied to the internal reforming units 4 via a second reforming unit in the form of a pre-reformer 3, in which the fuel gas supplied from the outside is first methanized in a manner known per se.
- the internal reforming units 4 are provided for generating more hydrogen than in the fuel cell 2 feasible.
- the Prereformer 3 is coolable. A part of the hydrogen-containing reformed fuel gas is withdrawn from the internal reforming units 4 and returned to the pre-reformer 3, wherein the water contained in the supplied reformed fuel gas in the pre-reformer 3 undergoes an exothermic reaction and the resulting heat is dissipated by cooling the pre-reformer 3.
- the pre-reformer 3 is thus provided in the embodiment shown here for receiving the fuel gas withdrawn from the internal reforming 4 together with fuel gas freshly supplied from the outside.
- a conveyor 5 For returning the withdrawn from the first reforming 4 fuel gas to the second reforming unit 3, a conveyor 5 is provided, for example, a Pump or a side channel compressor can be.
- the coolable pre-reformer 3 is for adjusting the strength and the course of the reverse reaction, i. the composition of the gases reacted therein, by adjusting the temperature by the amount of cooling provided.
- the fuel gas withdrawn from the internal reforming units 4 is supplied to the pre-reformer 3 together with the fuel gas freshly supplied from the outside.
- the endothermic reaction taking place in the internal reforming units 4 may inhibit the reactions
- the exothermic back reaction taking place in the preformer 3 can be the reaction
- the adjustment of the reverse reaction in the pre-reformer 3, i. the strength and the course of the reverse reaction and the composition of the gases reacted therein is done by adjusting the temperature by the amount of cooling.
