Method for increasing a temperature of a vehicle interior, and vehicle for implementing the method

A vehicle, comprising:

• a battery;
• a fuel cell system having a fuel cell stack;
• a compressor fluidically connected with the fuel cell stack at a cathode side via a cathode supply line;
• and
• an interior line that is fluidically connected with the cathode supply line and leads into a vehicle interior and that is present downstream of the compressor to supply at least a portion of a heated cathode gas mass flow into the vehicle interior, and
• wherein the vehicle is configured to draw in cathode gas via the compressor, compress and heat the drawn-in cathode gas, and supply the at least a portion of the heated cathode gas mass flow into the vehicle interior such that a temperature of the vehicle interior is raised to an increased temperature value.
