Description
Technical Field
The invention relates to the technical field of fuel cell vehicles, in particular to a hydrogen fuel cell stack mounting structure of a vehicle.
Background
Proton exchange membrane hydrogen fuel cells are widely favored in the fields of new energy automobiles, tramways, portable power sources, distributed power generation and the like due to the advantages of high energy conversion rate, no pollution, high starting speed, low operating temperature and the like.
A hydrogen fuel cell stack is a power generation device that converts externally supplied hydrogen and oxygen into electric energy, heat energy, and other reaction products through an electrochemical reaction, and accordingly, is provided with an input port for hydrogen as a fuel and an output port for surplus hydrogen, and an input port for air as a source of oxygen and an output port for air after reaction.
As shown in fig. 1, a current hydrogen fuel cell stack in a vehicle is generally disposed at an engine compartment position of the vehicle by a suspension device 5, an air inlet and an air outlet and a hydrogen inlet and an hydrogen outlet are disposed along a traveling direction of the vehicle, and an inlet 1 and an outlet 2 of air are located at the same level, and an inlet 3 and an outlet 4 of hydrogen are located at the same level.
The cathode of the hydrogen fuel cell stack can generate water in the reaction process, although most of the water is water vapor, a small part of the water is condensed into liquid water in an air flow channel, and if the liquid water is not discharged in time, the air channel can be blocked or permeate into the anode, so that the performance and the service life of the cell stack are influenced. Meanwhile, after the temperature of the anode end is reduced due to the pressure reduction and heat dissipation of the hydrogen, the mixing of the high/low temperature hydrogen at the inlet of the hydrogen also causes water vapor to be condensed into water vapor or water drops, and if the water vapor or the water drops are not discharged in time, the smooth circulation of the hydrogen is prevented, so that the normal reaction of the cell stack is influenced. The arrangement mode of the existing hydrogen fuel cell stack in the vehicle is not only not beneficial to the discharge of water in the hydrogen flow channel and the air flow channel, but also further aggravates the occurrence of a flooding phenomenon in the running process of the vehicle, particularly the starting and stopping process, and deteriorates the working condition of the hydrogen fuel cell stack.
