Abstract

The invention belongs to the technical field of hybrid electric vehicles, and discloses a fuel cell system and a fuel cell control method. The fuel cell system comprises a series mode and an independent mode; the fuel cell system comprises an electric pile, a heater, a first adjusting piece and a warm air core body which are communicated with one another, the first adjusting piece is arranged between the electric pile and the heater, and the first adjusting piece is configured to be selectively communicated with the electric pile and the warm air core body, so that the fuel cell system is switched between a series mode and an independent mode. The waste heat of the fuel cell system galvanic pile can be used for heating the warm air core body, the waste heat of the galvanic pile is fully utilized, the heater and the heat of the galvanic pile can be simultaneously used for carrying out warm air heating on the warm air core body, the performance is better, the energy consumption is low, and the advantages of energy conservation and environmental protection are achieved. Besides, the heater is used for heating the galvanic pile during cold start, so that the galvanic pile cold start and the warm air core body heating share the same heater, and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a fuel cell system and a fuel cell control method. Background technique [0002] With the development of hybrid electric vehicles, fuel cell vehicles, as one of the special hybrid electric vehicles, have received more and more attention. Fuel cell vehicles are generally equipped with two power sources, battery and electric stack. Electricity is generated, and during this process, the stack emits a large amount of heat and reaction by-products such as water. This heat needs to be dissipated by the radiator, and this heat can also be supplied to the warm air in winter. However, when only using the battery for pure electric mode, the battery stack does not work, so it cannot provide a heat source for the passenger compartment. [0003] In order to solve the above problems, the existing fuel cell systems generally adopt the following two methods: [0004] First, ...
