Date of Patent: April 7, Inventor: Hannes Scholz. Cathode supply for a fuel cell. Abstract: A cathode supply 30 for a fuel cell 10 of a fuel cell unit 1 for a fuel cell system is provided, the cathode supply 30 including a cathode supply path 31 and a cathode exhaust gas path 32 and at least two fluid pumping devices 33, for pumping a cathode operating medium 5 for the fuel cell 10 are fluido-mechanically coupled into the cathode supply path 31 , at least one first fluid pumping device of the at least two fluid pumping devices 33, being drivable only on the basis of an enthalpy in a cathode exhaust gas 6 of the fuel cell A fuel cell unit for a vehicle, in particular, an electric vehicle, a fuel cell system for a vehicle, in particular, an electric vehicle, or a vehicle in particular an electric vehicle, the fuel cell unit, the fuel cell system, or the vehicle including a cathode supply 30 is provided.
Filed: November 3, Date of Patent: November 19, Abstract: A bipolar plate for a fuel cell having two profiled separator plates with channels for reaction gases and coolant, wherein the channels for a reaction gas or both reaction gases have a smaller width in an inlet region of the active region than in the remaining sub-region of the active region, wherein the width thereof continuously increases from the beginning to the end of the inlet region.
Supports between the channels have a greater width than in the remaining sub-region of the active region, wherein the sum of the width of the channels and the width of the supports is constant, and the width of the channels and the supports is constant in the entire remaining sub-region.
Filed: June 20, Publication date: July 25, Abstract: The invention relates to a bipolar plate for a fuel cell, comprising an anode plate with anode gas channels and a cathode plate with cathode gas channels, said plates having an active region and supply regions and being arranged one over the other such that the gas channels form coolant channels.
The aim of the invention is to improve such a bipolar plate such that the flow conditions of reactants and coolant in the bipolar plate are optimized.
Filed: April 26, Publication date: May 2, Abstract: The invention relates to a method for producing a membrane electrode assembly 10 for a fuel cell, comprising the following steps in the order given: provide two gas diffusion layers 13 that each have a catalytically coated surface; apply an ionomer dispersion 15a onto the coated surface of at least one of the gas diffusion electrodes 13 , arrange the gas diffusion layers 13 on each other such that the coated surfaces face each other, and a layer stack 18 comprising a gas diffusion layer 13 -catalytic coating 14 -ionomer coating 15 -catalytic coating 14 -gas diffusion layer 13 arises, and arrange a peripheral seal 17 around the layer stack 18 , wherein the seal 17 has a height that at least corresponds to the height of the layer stack Furthermore, the invention relates to a membrane electrode assembly 10 that is or can be produced by means of the method according to the invention.
Filed: October 19, Publication date: February 28, Publication date: November 15, Abstract: The invention relates to a bipolar plate 10 for a fuel cell stack.
The bipolar plate 10 respectively has two profiled separator plates 12, 14 respectively having an active area 16 and two distribution areas 18, 20 for supplying and discharging reaction gases and coolant to or from the active area 16 , wherein the separator plates 12, 14 are designed and arranged on top of each other such that the respective bipolar plate 10 has separate channels 28, 30, 32 for the reaction gases and the coolant, which channels connect ports 22, 24, 26 for reaction gases and coolant of both distribution areas 18, 20 to each other.
In the mounted fuel cell stack, the channels 28, 30 for the reaction gases are respectively bordered by a surface of a separator plate 12, 14 and a surface of a gas diffusion layer Filed: August 10, Publication date: August 30, Abstract: The invention relates to a fuel cell stack 1 , comprising:—bipolar plates 10 , each having an active region 13a , wherein a surface of the bipolar plate is formed non-profiled at least in the active region 13a ,—a membrane electrode assembly 20 , arranged between two bipolar plates 10 , and—a gas distribution layer 30 arranged between the membrane electrode assembly 20 and at least one of the bipolar plates 10 , wherein the gas distribution layer 30 comprises a porous flow body Publication date: July 26, Publication date: June 28, Self-wetting membrane electrode unit and fuel cell having such a unit.
Abstract: A membrane electrode assembly and fuel cell having such assembly. The membrane electrode assembly has a polymer electrolyte membrane, two catalytic electrodes in contact with the polymer electrolyte membrane on both sides, namely an anode and a cathode, and two gas diffusion layers directly or indirectly adjoining the electrodes, namely an anode-side gas diffusion layer and a cathode-side gas diffusion layer.
At least one of the gas diffusion layers may optionally feature a microporous layer facing the polymer electrolyte membrane. The sequence of layers is anode-side gas diffusion layer, anode-side microporous layer, anode, polymer electrolyte membrane, cathode, cathode-side microporous layer, cathode-side gas diffusion layer.
