Definitions
- the invention relates to a high-temperature membrane (HTM) fuel cell, a method for operating an HTM fuel cell and an HTM fuel cell battery.
- HTM high-temperature membrane
- the polymer electrolyte membrane (PEM) fuel cell is known from the prior art, which has as the electrolyte a base polymer to which [-S0 3 H] groups are attached.
- the electrolytic conduction takes place via hydrated protons.
- this membrane needs liquid water, ie operating temperatures below 100 ° C. under normal pressure, in order to ensure the proton conductivity.
- One starting point to remove the limitation of the operating temperature is that instead of the membrane containing the [-SO3H] groups, another membrane is used, which may also be an ion exchange membrane, and / or a matrix with free and / or physically and / or chemically bound phosphoric acid is used as the electrolyte of a fuel cell.
- This fuel cell is called a high-temperature membrane fuel cell, which is referred to below as an HTM fuel cell.
- PAFC phosphoric acid fuel cell
- the object of the invention is therefore to create a fuel cell and to provide an associated operating concept. This is intended to build a fuel cell battery that can function without replenishing the electrolyte.
- the invention relates to a high-temperature membrane fuel cell, with a membrane and two electrodes, the anode and the cathode with the associated reaction gas spaces, one or both of the electrodes and / or one or both reaction gas spaces being at least locally heatable.
- the invention further relates to a method for operating an HTM fuel cell battery in the case of a Temperature of the fuel cell stack below 100 ° C at least one electrode and / or a reaction gas space is locally heated, so that the product water formed does not condense but leaves the fuel cell unit in gaseous form.
- the subject of the invention is an HTM fuel cell battery which comprises at least one fuel cell unit, the cathode, anode and / or one of whose reaction gas spaces can be heated.
- the cathode and / or the cathode space is preferably heated. Appropriate measures can also be carried out on the anode side of fuel cells.
- HTM high-temperature membrane
- a single fuel cell unit comprises a centrally arranged membrane with an electrode coating on both sides.
- the electrode coating contains a gas diffusion layer, which has, for example, a current collector made of a carbon fabric or the like, and a layer with the electrocatalyst which is directly adjacent to the membrane.
- the fuel cell unit is surrounded by a pole plate at the top and bottom, the pole plate also being referred to as a cell plate or bipolar plate.
- a stack of individual fuel cell units referred to in the art as a fuel cell stack, comprises at least one fuel cell with the corresponding end plates and
- the cooling system stem can also have components that are arranged outside the stack.
- a fuel cell battery comprises at least one fuel cell stack and associated units, which are also arranged in the battery, such as a reformer.
- the localized areas m which takes place this simulation, are preferably those areas where m the resulting product without water, the temperature increase was auskon ⁇ condense.
- the product water is produced in vapor form.
- the vaporous water is discharged, for example, with a gas stream, in particular the process gas stream of the fuel cell.
- the heating element is required for local heating to evaporate the process water at starting temperatures below 100 ° C.
- the heating element can be at least one wire which is embedded, for example, in the catalyst layer of the electrode, in the gas diffusion layer and / or in the pole plate or the cell plate or in the bipolar plate of the fuel cell unit.
- the wire is wound a resistance wire, for example serpentmenformig m or similar form, being produced by an electrical current in the resistor wire ⁇ 's heat.
- the catalyst layer serves ⁇ m connection with the electrode directly as a heating element, for example m the form of a catalytic burner, said fuel and oxidant from ⁇ partly, ie, 0 2 and / or air, are directed to the catalyst layer.
- a catalytic burner leads to a so-called silent combustion, which heats the reaction gas space.
- the catalyst layer in connection with the electrode, the gas diffusion layer and / or the pole plate itself serves directly as a heating element, for example by passing current through it.
- the heating element is only present in parts of the electrode, the pole plate and / or gas diffusion layer, so that these have areas that can be heated and areas that are unheatable.
- the electrical power emitted by the fuel cell battery itself or by an external battery is used for supply, with an additional battery possibly being provided for the fuel cell unit, the heating in the other cases takes place directly through the conversion of the chemical energy that is present in the fuel.
- the recombination of fuel gas and oxidant is used, which realizes an exothermic process.
