Fuel cell engine system integration scheme

Abstract

The invention relates to a fuel cell engine system integration scheme. The fuel cell engine system integration scheme comprises a galvanic pile package structure and a hydrogen treatment system, an exhaust system is distributed at one end of the galvanic pile package structure, and an intake system is distributed at the other end of the galvanic pile package structure. The hydrogen treatment system is distributed on one side of the lower end of the galvanic pile package structure, and a thermal management system is distributed on the other side of the lower end of the galvanic pile package structure. The fuel cell engine system integration scheme has the compact structure and can be used for A0-class vehicles; the safety performance is good, and the galvanic pile is packaged to ensure thatthe hydrogen leaked from the galvanic pile does not gather in an engine compartment; the engine can be started at a temperature of -25 DEG C. A cooling pipeline is highly integrated to reduce the capacity requirement of the whole vehicle water pump. The fuel cell engine system integration scheme has the protection level of IP67 through an upper air outlet and a lower air outlet, and the main function is to protect the galvanic pile from dust and rain, and ensure the normal operation of the galvanic pile.

Description

technical field [0001] The invention relates to the technical field of fuel cell engines, in particular to a fuel cell engine system integration solution. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials. In the automotive industry, fuel cell vehicles are developing rapidly in the industry due to their advantages of zero emissions, long mileage, and short refueling time. [0003] At present, commercial vehicles such as passenger cars and logistics vehicles have achieved ...
