Abstract

The invention discloses a commercial vehicle fuel cell system, and relates to the field of new energy vehicles. The problem that an existing system is low in integration degree and space utilization rate is solved. The system specifically comprises an integrated frame and an electric pile module. The outer wall of the top of the integrated frame is fixedly connected with a key component mechanism. The key component mechanism comprises an air treatment assembly, a hydrogen treatment assembly and a cooling assembly. The outer wall of the top of the key component mechanism is fixedly connected with a fuel cell assembly, and the top outer wall of the fuel cell assembly is fixedly connected with an electrical assembly. According to the fuel cell system, as a main framework of the system, the integrated frame is arranged and can achieve a supporting effect and fix the whole fuel cell system, and related elements can be fixed and disassembled in a detachable mode, so that assembly and maintenance of the system are greatly facilitated; and related parts can be arranged around the integrated frame, so that the integration level and the space utilization rate are improved.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a commercial vehicle fuel cell system. Background technique [0002] The fuel cell system is usually applied as a powertrain, but the system is still composed of multiple scattered components, and the overall integration level is not high. At present, although commercial vehicles are easy to arrange fuel cell systems due to their large space, more and more commercial vehicle OEMs also require high integration, high space utilization, and easy assembly and maintenance for system layout. [0003] After searching, the Chinese patent application number is CN201810042717.0, which discloses a commercial vehicle fuel cell thermal management system, including a controller, a hydrogen fuel cell system, an electronically controlled three-way valve, an electric heater, a radiator, and a frequency conversion fan , replenishment water tank, frequency conversion water pump, deionization dev...
