Abstract

The invention provides a proton exchange membrane fuel cell engine integrated device for a vehicle, and belongs to the technical field of fuel cell engines. The device comprises an electric pile module, an electric control module, and an air module, a hydrogen module and a cooling module which are positioned at the lower part of the electric pile module, the electric pile module comprises an electric pile module base plate of an integrated component, the air module comprises an air module bottom plate of the integrated component, the hydrogen module comprises a hydrogen module bottom plate of the integrated component, and the cooling module comprises a cooling module bottom plate of the integrated component. The air module bottom plate, the hydrogen module bottom plate and the cooling module bottom plate are fixed below the electric pile module bottom plate through structural parts, so that integration is realized; and the electric pile module is connected with all parts in the air module, the hydrogen module and the cooling module through pipeline interfaces. Energy optimization control and stable operation of the engine are achieved through modular design, the reliability of the engine is improved, the service life of the engine is prolonged, the integration level is high, and the device is suitable for buses.

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...
