Hydrogen Fuel Cell Vehicle（HFCV）

Hydrogen Fuel Cell Vehicles are a type of electric vehicle, whose battery energy is generated through the chemical reaction of hydrogen and oxygen, rather than being directly converted into electrical energy through combustion. The chemical reaction process of fuel cells does not produce harmful products, so hydrogen fuel cell vehicles are pollution-free vehicles. The energy conversion efficiency of fuel cells is 2-3 times higher than that of internal combustion engines. Therefore, in terms of energy utilization and environmental protection, fuel cell vehicles are an ideal vehicle.

Technology and Business
Trends

Clean energy alternative fuel oil：

Hydrogen, as a clean energy source that can store waste energy and promote the transition from traditional fossil fuels to green energy, has an energy density (140 MJ/kg) three times that of oil and 4.5 times that of coal. It is considered a disruptive technological direction for the future energy revolution.

Hydrogen fuel cell technology：

The low-cost production of basic materials for electrolytes and catalysts, as well as the research and development of related technologies for fuel cell structure and durability, are the main technological directions for promoting the large-scale application of hydrogen energy and hydrogen fuel cells.

Working Principle of
Hydrogen Fuel Cell Cooling

Single Liquid Cooling

Through the forced convection heat transfer of the coolant，the heat generated during the operation of PEMFC will be transmitted through the cooling channels inside the bipolar plate.Due to the fact that the coolant needs to flow through a bipolar plate with high potential, in order to ensure that high voltage will not be transmitted to the entire cooling cycle ， it is required that the coolant has high electrical insulation.

Phase Change Liquid Cooling

Eliminating waste heat in fuel cells through the enthalpy of vaporization. Unlike traditional cooling, phase change cooling can utilize the latent heat of the coolant and has unique advantages such as reducing coolant flow rate and simplifying system layout. The main methods include evaporative cooling, boiling two-phase cooling, and phase change material cooling.
