Definitions
- the present invention relates to a fuel cell system, in particular for a vehicle.
- Fuel cells are increasingly used as energy converters, including in vehicles, to convert chemical energy stored in a fuel, such as hydrogen, directly into electrical energy together with oxygen.
- Fuel cells typically have an anode, a cathode, and an electrolytic membrane positioned between the anode and the cathode. The fuel is oxidized at the anode and the oxygen is reduced at the cathode.
- Ambient air is usually supplied to the cathode for supplying oxygen, in that a compressor arranged in a supply line draws in air from the environment and supplies it to an air inlet of the fuel cell.
- air filter devices are typically used, which are arranged upstream of the compressor. Due to the compressor or other components arranged downstream of the air filter device, foreign substances can again enter the already filtered air.
- Situations arise in which air is drawn from one fuel cell system into the other fuel cell system without passing through the central air filter in a manner intended for this purpose.
- a fuel cell system with the features of claim 1 and a fuel cell system with the features of claim 5 are provided.
- a fuel cell system comprises a fuel cell arrangement with at least one fuel cell and an air inlet, a supply line connected to the air inlet, a central air filter device which is connected to an input of the supply line, a compressor which is arranged in the supply line and is set up for this purpose , drawing in ambient air through the central air filter device and conveying it through the supply line to the air inlet of the fuel cell arrangement, and a decentralized air filter device, which is arranged in the supply line between the compressor and the air inlet of the fuel cell arrangement.
- One idea on which this aspect of the invention is based is to provide a decentralized air filter in a respective supply line, in particular downstream of the compressor, in addition to a central filter device. This achieves the advantage that foreign matter, which is introduced into the air by the compressor itself, is at least partially separated by the decentralized air filter device. This prevents damage or contamination of the cathode of the fuel cell arrangement, which, for example, can be a stack with a large number of fuel cells.
- Another advantage is that when several fuel cell assemblies are connected in parallel to the central air filter, e.g. directly or via a distributor block, a decentralized filter device is provided in the supply line, which is connected to the air inlet of the respective fuel cell assembly.
- a decentralized filter device is provided in the supply line, which is connected to the air inlet of the respective fuel cell assembly.
- the air supplied to the respective fuel cell arrangement is filtered at least once in a defined manner, for example even when the air is sucked past the central air filter or through the central air filter against an intended flow direction.

- the fuel cell system can have the cooler and the humidifier, the humidifier being arranged between the cooler and the air inlet of the fuel cell arrangement, and the decentralized air filter device being arranged between the cooler and the humidifier.
- This arrangement offers the advantage of air already cooled by the cooler, but still has a relatively low level of humidity. This achieves a particularly efficient filtering of the air and at the same time the wear of the filter is further reduced.
- a fuel cell system comprises a plurality of fuel cell assemblies, each of which has at least one fuel cell and an air inlet, a central air filter device and a plurality of supply lines, each of which is connected to the central air filter device and to the air inlet of a fuel cell assembly, wherein A compressor is arranged in each supply line, which is designed to draw in ambient air through the central air filter device and to convey it through the respective supply line to the air inlet of the respective fuel cell arrangement.
- the fuel cell system also has a decentralized filter system, which is set up to filter air, which is conveyed by a respective compressor to the respective air inlet, downstream of the central filter device.
- One idea underlying this aspect of the invention is to provide a decentralized filter system in a fuel cell system with at least two fuel cell arrangements that are connected in parallel to one another, e.g. directly or via a distributor block, which is set up to filter air from a respective compressor is sucked in via a flow path which runs past the central air filter device or runs through it counter to an intended flow direction.
- the decentralized filter system can have, for example, one or more filter units, which are arranged downstream of a filter unit of the central air filter device.
- the decentralized air filter system is that the air supplied to the respective fuel cell arrangement is always filtered at least once in a defined manner, for example even when the air is sucked past the central air filter or through the central air filter against an intended flow direction.
- the filter unit of the central air filter device and the filter unit(s) of the decentralized air filter system can be accommodated in a common housing. This advantageously results in a compact structure.

- the central filter unit and the filter unit(s) of the decentralized filter system can thus be combined into a single filter unit.
- the cartridge can have a first section, which is connected to the inlet of the central filter device, and a second section, the second section being connected to the outlets of the central filter device.
- the first section may be arranged to filter air drawn in through the inlet of the central filter device and the second section may be arranged to filter air drawn in through one of the outlets of the central filter device.
