Embodiment Construction

[0022] exist figure 1 A fuel cell system 10 for a motor vehicle according to a first embodiment of the present invention is shown in . The fuel cell system 10 includes a cooling module 14 , an electric drive module 18 , a fuel tank module 22 and a fuel cell device 26 . The cooling module 14 , the electric drive module 18 and the fuel tank module 22 are here vehicle-specifically adapted for connection to connections of the motor vehicle. The cooling module 14 here has a cooling circuit by means of which the cooling medium can be cooled. The electric drive module 18 includes at least one electric drive motor with which the motor vehicle can be driven and optionally has a high-voltage energy store in which electrical energy can be stored. The fuel required for the fuel cell 30 is stored in the fuel tank module 22 .

[0023] The fuel cell arrangement 26 includes a fuel cell 30 , which is connectable to the electric drive module 18 via a power connection 34 and supplies the elec...

Abstract

The present invention relates to a fuel cell system (10) for a motor vehicle, and to a motor vehicle which has a fuel cell system (10) of this kind. In this case, the fuel cell system (10) comprises acooling module (14), an electrical drive module (18), a fuel tank module (22) and at least one fuel cell apparatus (26). In this case, the fuel cell apparatus (26) comprises a fuel cell (30), a cooling connection unit (38) which is connected to the fuel cell (30), wherein the cooling connection unit (38) has cooling connections (50) by way of which the fuel cell apparatus (26) can be connected tothe cooling module (14) so that the fuel cell apparatus (26) can be cooled by means of the cooling module (14), power connections (34) which are connected to the fuel cell (30) so that the fuel cellapparatus (26) can be connected to the electrical drive module (18) and the electrical drive module (18) can be supplied with power, an air connection unit (54) which is connected to the fuel cell (30), wherein the air connection unit (54) has air connections (62) by means of which air can be supplied to and discharged from the fuel cell apparatus (26), and a fuel supply unit (66) which is connected to the fuel cell (30), wherein the fuel supply unit (66) has a fuel connection (70) by way of which the fuel cell apparatus (26) can be connected to the fuel tank module (74) so that fuel can be supplied to the fuel cell (30).

Description

technical field [0001] The invention relates to a fuel cell system for a motor vehicle and to a motor vehicle with such a fuel cell system. Background technique [0002] Fuel cell systems are used in particular in fuel cell vehicles. In the vehicle, fuel is converted into electrical energy via a fuel cell in order to drive an electric drive motor and / or charge an energy store. In order to ensure the operation of the fuel cell, the fuel cell is connected here to the fuel tank via a quantity-controlled fuel path. In this case, the current is conducted via the circuit either into the electrical energy store or into the electric drive motor as required. Advantageously, the fuel cell is connected to a cooling system so that the fuel cell can come to operating temperature more quickly, or the cooling system can cool the fuel cell. [0003] A fuel cell system for an electric hybrid vehicle or a fuel cell vehicle is known from DE 10 2011 076 737 A1. [0004] The background of th...
