Abstract

The invention discloses a commercial vehicle fuel cell engine air supplying system. The system comprises an internal resistance detector, a controller, a fuel battery voltaic pile, a hydrogen supplying system and an air supplying system. The commercial vehicle fuel cell engine air supplying system has the advantages that the recycling of hydrogen is achieved, the supplying flow rate and pressure of the hydrogen and air can be accurately controlled, and therefore sustainable and stable power generation of a fuel cell can be ensured; the internal resistance of the fuel cell voltaic pile can be detected to judge the humidity of a proton exchange membrane, internal water management of the fuel cell is effectively conducted by adjusting the opening degree of a tail discharging valve and a humidifying valve, and the efficiency and output performance of the fuel cell are improved.

Description

technical field [0001] The invention belongs to the technical field of fuel cell engines, and in particular relates to an air supply system for commercial vehicle fuel cell engines. Background technique [0002] Fuel cell engine is the main power source of fuel cell vehicles. It is a high-efficiency power generation device that directly converts the chemical energy of fuel into electrical energy by electrochemical reaction without burning fuel. Its core component is a fuel cell stack composed of multiple single cells in series, and it is also equipped with a hydrogen supply system, an air supply system, a water and heat management system, and a control system. Only when these auxiliary systems are properly matched and functioning normally can the normal operation of the fuel cell engine be guaranteed. The hydrogen supply system and the air supply system provide enough oxidants and reductants for the stack to generate electricity. The electrochemical reaction between hydroge...
