(EN) Although the basic principle of the fuel cell has already long been known, intensive developments always result in novel aspects of the practical realization of the fuel cell. The invention proposes a supply system (3) for a fuel cell stack (2) with a cathode gas supply line for supplying an ox ...
Liquid cooled systems having coolant circulation loops (136) must often operate in below freezing conditions. For instance, in various applications certain fuel cell systems (10) must be able to tolerate repeated shutdown and storage in below freezing conditions. Conventional glycol-based coolants t ...
The invention relates to a fuel cell system for a vehicle, having a burner (33) for producing a heat flow by combustion of a fuel gas (13) which reacts with an oxidant (24). According to the invention, a heating heat exchanger (43), which is provided in order to heat a vehicle passenger compartment, ...
(EN) The invention relates to a fuel cell system (10) with a plurality of fuel cells which are assembled to form a stack (12),with a cathode side (16), which has a cathode input (16a) for supplying an at least oxygen-containing gas and a cathode output (16b), and with an anode side (14), with an ano ...
Device for driving a vehicle, comprising an electrical drive motor (5) and a fuel cell (2) providing the electrical power. The drive motor and the fuel cell are integrated into a unit (1) and firmly joined together.
A fuel cell system and a vehicle having a fuel cell system with improved operating behaviour, in particular for cold or sub-freezing starting, is disclosed. A fuel cell system (1) is proposed having at least one fuel cell stack (2), which comprises a plurality of plate-shaped fuel cells (10), and ha ...
The invention relates to a fuel cell (1), in particular for arrangement in a fuel cell stack, having a first bipolar plate (2) and a second bipolar plate (3) and having a membrane electrode assembly (4), which is arranged between the two bipolar plates (2, 3) arranged plane-parallel to one another, ...
In a fuel cell system (10), the transfer of thermal energy between individual components is deliberately promoted, in particular between the fuel cell stack (12) and the anode unit (14). In this way icing is prevented, since as a result of the thermal coupling no local heat sinks, on which water is ...
In fuel cell systems, air is compressed in an air delivery means (12) and fed via a humidifier (18) to a fuel cell stack (10). It is known in the prior art to branch a bypass line (26) off from the lines between compressor (12) and humidifier (18) or humidifier (18) and fuel cell stack (10), in orde ...
The invention relates to a method and an apparatus for operation of a fuel cell arrangement (1) having a plurality of fuel cells which are combined to form a stack (2) and have a common cathode input (3.1) and cathode output (3.2), as well as a common anode input (4.1) and anode output (4.2), and ha ...
