Embodiment Construction

[0036] Figure 1a A schematic illustration of a fuel cell system 2 is shown. The fuel cell system has a fuel cell unit 4 which, for example, has a plurality of individual (not individually shown) fuel cells which together form a connected unit, for example in the form of a fuel cell stack. In order to supply the electrical consumers with voltage, the fuel cell unit 4 is provided with electrical conductors 6 which, when the fuel cell system 2 is installed in an aircraft, can be connected, for example, to an on-board electrical network of the aircraft. In order to supply fuel (for example hydrogen) to the fuel cell unit 4, an anode inlet 8 and an anode outlet 10 are provided.

[0037] Furthermore, the fuel cell unit 4 has an inflow section 12 and an outflow section 14 for enabling air to flow through an open cathode 16 of the fuel cell unit 4 . The first fluid chamber 18 is directly connected to the inflow section 12 , which first fluid chamber has a first connection opening 20...

Abstract

In a fuel cell system (2) intended for a pressure-independent operation, in which at least one fuel cell having an open cathode is provided, a first fluid chamber (18) adjoins an inflow cross sectionand a second fluid chamber (32) adjoins an outflow cross section (14). In the fluid chambers (18, 32) can be set an overpressure which is adapted to the operation of the at least one fuel cell.

Description

technical field [0001] The invention relates to a fuel cell system for an aircraft and an aircraft equipped with such a fuel cell system. Background technique [0002] The use of fuel cells in aircraft is known. Various solutions exist for integrating fuel cells into aircraft. The use of PEM fuel cells is in particular combined with conditions which involve, inter alia, the observance of certain boundary conditions. For example, the supplied reactants should as far as possible not exceed a temperature of about 40°C to 50°C. It should also be possible to maintain membrane humidity. [0003] Furthermore, it is very advantageous to use fuel cell stacks with air-cooled (so-called open) cathodes. However, due to the type of structure, operations are limited to altitudes below about 4000m. Operation at near ground level is only possible if such a fuel cell is used in an aircraft and is located in the non-pressurized region of the fuselage. [0004] DE 10 2005 010 399 A1 show...
