Description

A hydrogen fuel cell dump truck chassis structure

Technical field

The utility model belongs to the technical field of commercial vehicle chassis, specifically a hydrogen fuel cell dump truck chassis structure.

Background technique

A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzing water, supplying hydrogen and oxygen to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load.

Hydrogen fuel cells have the following advantages:

1. No pollution. Hydrogen fuel cells do not pollute the environment. It is through electrochemical reaction rather than using combustion (gasoline, diesel) or energy storage (battery) - the most typical traditional backup power solution. Combustion releases pollutants like COx, NOx, SOx gases and dust. As mentioned above, fuel cells only produce water and heat. If the hydrogen is produced from renewable energy sources (photovoltaic panels, wind power, etc.), the entire cycle is completely emission-free.

2. No noise. Hydrogen fuel cells operate quietly, with only about 55dB of noise, which is equivalent to the level of a normal conversation. This makes the fuel cell suitable for indoor installation, or where there are restrictions on outdoor noise.

3. High efficiency. The power generation efficiency of hydrogen fuel cells can reach more than 50%. This is determined by the conversion properties of the fuel cell, which directly converts chemical energy into electrical energy without the need for intermediate conversion of thermal energy and mechanical energy (generator).
