Fuel Cell Vehicle Coolants Performance Fluids Dober

NEW ENERGY COOLANTS

ENSURE OPTIMAL PERFORMANCE AND EXTEND THE LONGEVITY OF YOUR FUEL CELL VEHICLES

Long-haul trucks, buses, delivery vehicles and other heavier-duty vehicles will begin to make the switch from diesel to fuel cell technology and hydrogen.

Those vehicles will need a coolant formulated specifically to maintain the fuel cell stack and keep those vehicles going for hundreds of thousands of miles. That coolant needs to offer:

Low electrical conductivity
Good thermal conductivity
Corrosion inhibition
Material compatibility

WHY DO FUEL CELL VEHICLES NEED CORROSION INHIBITION TECHNOLOGY?

Fuel cell vehicles, whether long-haul trucks, buses, delivery vehicles or otherwise, need corrosion protection.

Like battery electric vehicles, fuel cell vehicles contain different materials in the fuel cell stack — in simple terms, the engine — than their internal combustion engine predecessors. Furthermore, various fuel cell OEMs might prefer different materials from their competitors. Those materials include stainless steel alloys, aluminum alloys, platinum, polymers and EPDM rubber.

The fuel cell stack is a complicated system that requires corrosion protection, or you risk decreasing the life of the deionizing filter and, potentially, safety hazards.

DESIGNED for NEAR-ZERO ELECTRICAL CONDUCTIVITY Fuel cell VEHICLES need

When it comes to electrical conductivity, the specs are even stricter for fuel cell vehicles than they are for electric vehicles.

Legacy ICE engines require coolants to be somewhere in the range of 2,000-4,000 microsiemens per centimeter (μS/cm). Meanwhile, many battery electric manufacturers ask for electrical conductivity well below 100 μS/cm.

But what about fuel cell vehicles?

Fuel cell vehicles will require electrical conductivity of less than 5 microsiemens per centimeter (µ/cm).
