Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] like figure 1 Shown is a structural diagram of a conventional fuel cell system. The hydrogen storage device 1 is connected to the main fuel cell 10 through a first hydrogen supply pipeline to supply hydrogen to the main fuel cell 10. A first control system is arranged in series on the first hydrogen supply pipeline. The valve 4 and the air compressor 2 are connected to the main fuel cell 10 through the first air supply pipeline to provide air to the main fuel cell 10, and the third control valve 5 is arranged in series on the first air supply pipeline. The hydrogen supply output pipeline of the main fuel cell 10 exhausts the tail gas through the hydrogen exhaust valve 17, and connects the first hydrogen supply pipeline through the hydrogen c...

Abstract

The invention relates to a vehicle and a fuel cell system. The fuel cell system comprises a main fuel cell and an auxiliary fuel cell and further comprises a hydrogen-supplying circulation system, anair-supplying circulation system and a cooling circulation system which are shared, the fuel cell system further comprises an electric heating device arranged in the cooling circulation system, and the auxiliary fuel cell is in electricity-supplying connection with the electric heating device. According to the fuel cell system, through the small-power auxiliary fuel cell, low-temperature startingof the main fuel cell is completed in the situation of less energy consumption, the problem that when the fuel cells are started at the low temperature, lots of vehicle-mounted energy devices need tobe consumed is solved, and low-temperature starting of the fuel cells can be achieved conveniently and rapidly.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a vehicle and a fuel cell system. Background technique [0002] Under the dual pressure of energy and environment, fuel cell vehicles have become the direction of the future development of the automobile industry and the focus of research in the field of automobiles. In order to adapt to the ever-changing all-weather and all-regional working conditions, the on-board fuel cell must have good cold start (ie low temperature start) characteristics. The biggest problem of cold start is that water forms ice at low temperature, which hinders the diffusion of hydrogen and air inside the membrane electrode (MEA) and the removal of water generated by the PEMFC cathode of the proton exchange membrane fuel cell, resulting in the failure of cold start. [0003] The strategies for low-temperature start-up of fuel cells are divided into two broad categories, namely the ...
