Embodiment Construction

[0048] figure 1A fuel cell system 1 for a vehicle is shown, wherein the fuel cell system 1 is suitable for raising the temperature of a vehicle interior from a low temperature value to an elevated temperature value and for driving the vehicle. Here, the fuel cell system 1 has a fuel cell stack 2 , the cathode chamber of which can be closed on the cathode inlet side 8 by means of a first adjustment element 9 formed as a first shut-off valve and is connected to the humidifier via the cathode supply line 4 . 10 phase connections. The cathode chamber can be closed on the cathode exit side 11 by means of a second adjustment element 12 in the form of a second shut-off valve and is connected to the humidifier 10 via a discharge line 13 . Furthermore, the fuel cell system 1 comprises a compressor 3 , which can be driven via a drive means 22 , via which dry cathode gas can be fed to the humidifier 10 as a cathode gas mass flow. Furthermore, an exhaust gas line 14 is associated with t...

Abstract

The disclosure relates to a method for increasing a temperature of a vehicle interior of a vehicle from a low temperature value to an increased temperature value, wherein the vehicle has a fuel cell system (1) with a fuel cell stack (2) and a compressor (3) connected with the fuel cell stack at the cathode side, comprising: drawing in cathode gas via the compressor (3), and compressing and heatingthe drawn-in cathode gas. At least a portion of a cathode gas mass flow of the heated cathode gas is directed into the vehicle interior, and the temperature of the vehicle interior is raised to the increased temperature value. Moreover, the disclosure relates to a vehicle for implementing the method.

Description

technical field [0001] The invention relates to a method for raising the temperature of the vehicle interior of a vehicle from a low temperature value to an elevated temperature value, wherein the vehicle has a fuel cell system with a fuel cell stack and with a A compressor connected to a fuel cell stack (Brennstoffzellenstapel). The method comprises the steps of drawing in cathode gas by means of a compressor, and compressing and heating the drawn in cathode gas. [0002] Furthermore, the invention relates to a vehicle for carrying out the method with a battery, with a fuel cell system with a fuel cell stack, and with a compressor that is fluidly connected to the fuel cell stack on the cathode side via a cathode supply line. Background technique [0003] Document DE 10 101 914 A1 describes a device and a method for a fuel cell facility vehicle (Brennstoffzellenanlagenfahrzeug) with a compressor which sucks in, compresses the ambient air and puts the heated ambient The amb...
