Embodiment Construction

[0021] The fuel cell engine system can be divided into electric stack, power control unit (PCU), motor, gearbox, fuel cell system (FCS) water pump and its controller, PCU water pump and its controller, air system, air conditioning compressor related, electric Heap control module.

[0022] The FCS water pump and water circuit supply water to the stack; the air circuit supplies air to the stack; the hydrogen circuit supplies hydrogen to the stack. The stack generates electricity through chemical action to supply the PCU.

[0023] The PCU receives power from the electric stack and the power battery (the power battery is connected to the PCU through a high-voltage line to supply power to the PCU). The PCU processes the received power and supplies it to the motor, air compressor controller, FCS water pump and its controller, PCU water pump and its controller, high-pressure fan, air-conditioning compressor, etc.; the PCU water pump and water supply cooling to the PCU water.

Abstract

The invention provides a fuel cell engine system integrated structure which includes an electric pile, an air system, a water system, a hydrogen system, a power control unit and an electro-driving system. The fuel cell engine system integrated structure also includes a framework, which is constructed in a manner that the electric pile, the air system, the water system, the power control unit and the electro-driving system can be arranged on the framework in a multilayer arrangement, wherein the electric pile is arranged at the center of the framework, the power control unit is disposed on the top layer of the framework, and the rest other parts of the fuel cell engine system are fixed on the framework in an arrangement of surrounding the electric pile. The electric pile, the power control unit and the rest other parts of the fuel cell engine system are all fixed on the framework respectively in a detachable manner. The parts in the integrated structure are easy to maintain and detach.

Description

technical field [0001] The invention relates to automobile technology, in particular to the integration of fuel cell engine systems. Background technique [0002] Power system development is one of the core contents of fuel cell vehicle research and development. The fuel cell vehicle power system includes fuel cell engine subsystems, electric drive subsystems, energy conversion and energy management subsystems, and corresponding auxiliary systems. As far as the development status of the fuel cell vehicle power system is concerned, the system is huge but the integration of each subsystem is very low, and the integration of the entire power system is very low. [0003] Domestic fuel cell vehicle vehicle design adopts decentralized arrangement for the power system of fuel cell vehicles, and uses brackets to fix each component, which is unreasonable for the industrialization of fuel cell vehicles. There are mainly two problems. First, it cannot meet the requirements of vehicl...
