摘要： Gas diffusion electrodes with improved proton conduction between an electrocatalyst located in a catalyst layer and an adjacent polymer electrolyte membrane, capable of being used at operating temperatures up to or above the boiling point of water, ensuring lasting high gas permeability. Also, a production method and corresponding fuel cells. At least one part of the particles of an electrically conductive carrier material in the catalyst layer is at least partially loaded with at least one porous, proton-conducting polymer which can be used up to or above the boiling point of water. Loading and development of the porous structure is carried out in a phase inversion method. The gas diffusion electrodes can be used in high temperature fuel cells working at temperatures up to or above the boiling temperature of water without a drop in performance in continuous operation.

摘要： A membrane electrode assembly (MEA) for a fuel cell, which has a planar polymer membrane. This membrane, in a tangentially inner area, is coated on both sides with electrode structure, and, in a tangentially outer area projecting at least on one side beyond the electrode structure coating, is connected to a sealing member. A marginal zone of the polymer membrane is embedded in the elastomer sealing member. The sealing member extends tangentially inward to a transition area that lies tangentially between the outer area and the inner area, where it overlaps the electrode structures on outer faces of the electrode structures, on both of the sides of the polymer membrane.

摘要： A membrane for fuel cells, which is characterized by a homogeneous absorption and good retention of doping agents, and which guarantees a high mechanical stability at high temperatures when doped. Such membranes consist of at least one polymer, whose nitrogen atoms are chemically bonded to a central atom of a derivative of a polybasic inorganic oxo acid. The membranes are produced from polymer solutions that are devoid of water and oxo acid derivatives, by heating the solution that has been introduced into a membrane mold until a self-supporting membrane has been formed and then by thermally regulating the latter. Inventive fuel cells having a membrane electrode assembly (MEA) that comprises a membrane of the invention and phosphoric acid as the doping agent have, for example, an impedance of 0.5-1 Ωcm2 at a measuring frequency of 1000 Hz and at an operating temperature of 160° C. and a gas flow for hydrogen of 170 mL/min and for air of 570 mL/min. They can be used as high-temperature polyelectrolyte membrane fuel cells for a working temperature of up to at least 250° C.

摘要： The invention relates to an insulating element for a fuel cell stack, which is composed of a thermally insulating plastic or plastic composite material. The insulating element is connected to the end plate and the bipolar end plate of the stack and achieves virtually uniform distribution of temperature and flow density along the fuel cell stack in the cell operating mode. As a result, the condensation of product water is prevented. The efficiency of the fuel cell stack is increased since it is possible to dispense with external heating of the stack by a cell current and costly measuring and control technology,
