Definitions
- the present invention relates to fuel cell assemblies and systems, comprising a catalytic exhaust gas burner for combustion of a mixture of anode residual gas, air and / or other admixed gases (eg cathode exhaust gas), wherein a mixed oxide catalyst comprising Cu and Mn is used as the catalyst in the exhaust gas burner, and a method and a use for this.
- a catalytic exhaust gas burner for combustion of a mixture of anode residual gas, air and / or other admixed gases (eg cathode exhaust gas)
- a mixed oxide catalyst comprising Cu and Mn is used as the catalyst in the exhaust gas burner
- Fuel cells offer the possibility of generating electricity from the controlled combustion of hydrogen at high efficiency. At present, however, there is no infrastructure for the future energy source hydrogen. Therefore, there is a need to extract hydrogen from the well-available energy sources natural gas, gasoline, diesel or other hydrocarbons such as biogas, methanol, etc.
- Methane - the predominant component of natural gas - can be used to generate hydrogen, for example by steam reforming.
- the resulting gas contains traces of unreacted methane and water, essentially hydrogen, carbon dioxide and carbon monoxide.
- This gas can be used as fuel gas for a fuel cell. In order to shift the equilibrium in the steam reforming on the side of the hydrogen, this is carried out at temperatures of about 500 0 C - 1000 0 C, wherein for a constant composition of the fuel gas, this temperature range should be maintained as accurately as possible.
- sulfur compounds present in the fuel gas are removed prior to delivery to the fuel cell because most of the fuel cell catalysts used are susceptible to sulfur.
- a fuel cell arrangement in which the fuel gas produced from methane and water can be used to generate energy is described for example in DE 197 43 075 A1.
- Such an arrangement includes a number of fuel cells disposed in a fuel cell stack within a closed protective housing.
- fuel gas Via an anode gas inlet fuel gas is supplied to the fuel cell, which consists essentially of hydrogen, carbon dioxide, carbon monoxide and residues of methane and water.
- the Fuel gas is generated either in an upstream external reformer or in an internal reformer of methane and water. Internal reforming reactions are often used in high-temperature fuel cells such.
- MCFC Molten Carbonate Fuel Cell
- SOFC Solid Oxide Fuel Cell
- the anode exhaust gas contains, in addition to the reaction products carbon dioxide and water, portions of hydrogen, carbon monoxide and methane gas, depending on the operating state and operating time.
- the anode exhaust gas is first mixed with air and then fed to a catalytic exhaust gas burner, in which the remaining methane and traces of hydrogen burned to water and carbon dioxide become.

- B. cathode exhaust gas are admixed.
- the released thermal energy can be used in various ways.
- precious metals such as platinum and / or palladium
- This catalytic combustion has the advantage that it is very uniform and without temperature peaks.
- the combustion of palladium catalysts proceeds at temperatures ranging from about 450 to 550 0 C.
- the equilibrium shifts Pd / PdO favor of palladium metal whereby the activity of the catalyst decreases (see Catalysis Today 47 (1999) 29-44).
- a loss of activity is also observed by the occurrence of sintering or the caking of the catalyst particles.
- noble metal catalysts have the disadvantage of very high raw material prices.
- EP 0 270 203 A1 discloses heat-stable catalysts for the catalytic combustion of, for example, methane. These are based on alkaline earth hexaaluminates which contain fractions of Mn, Co, Fe, Ni, Cu or Cr. These catalysts are characterized by a high activity and resistance even at temperatures of more than 1200 0 C. However, the activity of the catalyst is relatively low at lower temperatures. In order to be able to provide sufficient catalytic activity even at lower temperatures, small amounts of platinum metals are added, for example Pt, Ru, Rh or Pd.
- the ideal temperature range for operating a high temperature fuel cell is in the range of about 400 to 1000 ° C.
- the heat generated during anode-off-gas combustion can be used in various applications, for example, to evaporate water for steam reforming, providing heat energy for endothermic steam reforming , Heat utilization in cogeneration applications or the like.
- the completely oxidized anode exhaust gas which in particular no longer contains hydrogen gas, can be fed to the cathode as cathode gas after it leaves the burner. This is described for example in DE 197 43 075 A1

- oxidation catalysts comprising mixed oxides of copper, manganese and optionally one or more rare earth metal (s) are particularly suitable for this purpose.
