When did we start to develop Hydrogen Fuel Cell Cooling Systems?
GTS started to develop a Hydrogen Fuel Cell Cooling System in 2017 for Solaris, one of the largest city bus OEMs in Europe.
Our Hydrogen Fuel Cell Cooling System is an extension of the range of GTS Electric Fan Cooling Systems.
What is a hydrogen fuel cell?
A hydrogen fuel cell uses the chemical energy of hydrogen to produce electricity. It is a clean form of energy with electricity, heat, and water being the only products and by-products.
Why did we develop hydrogen fuel cell cooling systems?
Our customers’ vehicles are converting to alternative forms of energy. Rather than petrol and diesel engines, they are converting to battery electric vehicles.
Hydrogen fuel cells are used to generate electricity to charge batteries, this enables vehicles to use battery power to drive using an electric motor, rather than an internal combustion engine.
A hydrogen fuel cell needs cooling (just like traditional diesel and petrol engines do) to dissipate waste heat.
GTS has utilised existing electric fan cooling system technology, also known as E-drive, to cool the hydrogen fuel cells. The development and demand for HFCs are rapidly increasing due to customers developing new vehicles which will help towards meeting decarbonisation targets and legislation.
What are the key components of a Hydrogen Fuel Cell Cooling Systems?
Radiator – To cool the coolant to allow the fuel cell to maintain its temperature
Pump – Circulates the coolant around the fuel cell cooling circuit
Fans – takes cold air from outside the vehicle. The air blows through the radiator cores to cool the coolant down.
Harnesses – connects all of the electric fans from the hydrogen fuel cell cooler to the vehicle power supply.
The controller – is the brain of the system. It controls the speed of the fans depending on the cooling requirement. If the coolant inside the radiator cores do not need cooling down, the fans will remain off. If the coolant does need cooling, the fans will start spinning and the speed will be determined by the temperature of the coolant
What application do we supply Hydrogen Fuel Cell Cooling Systems to?
- Buses
- Coaches
- Trucks
The biggest Hydrogen Fuel Cell Cooling System we have developed to date is for our customer Solaris, it is used on an 18m hydrogen fuel cell bus. It is a 9-fan cooler that was mounted to the roof. We have also sold prototypes to Intertanker in Hungary and there is an on-going project with Wrightbus to look at the same cooling system.
