Description

Fuel cell pack

Technical Field

The utility model relates to a fuel cell protection equipment, in particular to fuel cell package.

Background

The principle of the fuel cell is an electrochemical device, and the composition of the fuel cell is the same as that of a general battery. The hydrogen fuel cell has the advantages of high fuel energy conversion rate, low noise, zero emission and the like, and can be widely applied to vehicles such as automobiles, airplanes and trains, fixed power stations and the like. Under the condition of relatively low coal-electricity ratio in the future, the whole upstream power supply structure is cleaner and cleaner due to the increase of the technical scale of renewable energy sources such as wind energy, solar energy and the like. Under the structure, the emission intensity of new energy automobiles, particularly pure electric automobiles and fuel cell automobiles based on hydrogen production by water electrolysis can be obviously reduced. The fuel cell vehicle is different from a pure electric vehicle in that the separation of upstream power generation and terminal power utilization in time is realized, and further, the complementary capability of hydrogen energy is stronger compared with wind energy and solar energy with higher volatility (pure electric vehicle technical route).

Under certain use environment and requirements, the fuel cell needs to have dustproof and waterproof performance, which requires that the sealing performance of the fuel cell is better and the waterproof and dustproof performance of the fuel cell is improved, and generally adopts a method of adding a protective shell outside the fuel cell. Because the whole weight of the battery pile is generally over 100kg, in order to ensure the strength of the shell, the shell is generally made of metal, but the all-metal shell is heavy in weight and inconvenient to operate in the production and assembly processes, and the strength of the shell cannot be ensured by adopting all-plastic parts.
