Description

technical field [0001] The invention belongs to the technical field of fuel cell engines, in particular to a proton exchange membrane fuel cell engine integration device for vehicles. Background technique [0002] A fuel cell is an environmentally friendly, high-efficiency, long-life power generation device. Taking the proton exchange membrane fuel cell (PEMFC) as an example, fuel gas enters from the anode side, hydrogen atoms lose electrons at the anode and become protons, protons pass through the proton exchange membrane to the cathode, and electrons also reach the cathode through an external circuit, protons, electrons Combines with oxygen at the cathode to form water. The fuel cell converts chemical energy into electrical energy in a non-combustion manner, and its direct power generation efficiency can be as high as 45% because it is not limited by the Carnot cycle. With the battery stack as the core power generation device, the fuel cell system integrates power manage...

AI Technical Summary

Problems solved by technology

However, the integration of fuel cell engines in existing commercial buses is low, and the functions are not complete. Additional auxiliary components and corresponding space requirements need to be added during loading, which is not conducive to the integration of vehicle loading.

In addition, the engine lacks a modular system design concept, resulting in difficulties in engine maintenance
