low-conductivity coolant formulated for fuel cells
THE FUTURE IS HERE.
FUEL CELL VEHICLES NEED A
FOR FUEL CELL CONDITIONS.
Why Dober? research, experience, agility — and much more.
Dober has been in business since 1957, boasting decades of experience and R&D know-how across a variety of chemical fields, including pharmaceutical, cooling tower chemicals, water treatment and to automotive performance fluids.
But as we reflect on the past, it's vital to prepare for the future — particularly the future of automobiles.
For much of the heavy-duty automotive sector, that means fuel cell vehicles.
Backed by research and testing, Dober offers a fuel cell coolant, FC ULC (Ultra-Low Conductivity).
With that in mind, you might be thinking to yourself that you might not have heard of us — and that's OK.
We believe in our product and look forward to sharing why we do. In turn, we hope we'll earn your trust.
Backed by our robust R&D processes and testing (including an ever-growing database of material compatibility data), we think you'll see why we're so optimistic about the future and why we think Dober should be a part of your fuel-cell future.

What makes an effective one?
In this e-book, we review what you need to know about the important characteristics of a coolant formulated specifically for fuel cell applications.
a fuel cell vehicle future
While battery electric vehicles have started to gain favor in the everyday passenger vehicle market, the fuel cell vehicle future will likely be found elsewhere.
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.
Long-haul trucks, which carry many of our basic necessities across highways and through locales urban and rural, are primed for a hydrogen renaissance. WIth fuel cell technology, trucking operations can save on maintenance and fuel costs.
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.

DOBER'S FC ULC COOLANT VS. THE COMPETITION
Dober FC ULC coolant (Fig. 1) vs. a competitor fuel cell coolant (Fig. 2) coupon tested at:
- 88° C
- For 14 days
- Metals tested: Stainless Steel 304, Copper, Brass, Stainless Steel 316L, Aluminum Alloy 6061
Fuel cell vehicles need protection of different materials throughout the fuel cell stack (compared with legacy ICE vehicles).
With Dober's material compatibility testing, have peace of mind that your coolant is protecting what it needs to protect. Test your materials with Dober (we might even already have testing data for your materials).
DESIGNED for the 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).
BACKED BY RESEARCH
We test our coolant solutions using a vessel where we heat it up to a high temperature and observe how the coolant ages over time. By looking at how well the active ingredients hold up and if the pH and electrical conductivity remain stable during the tests, we’re able to optimize the chemistry for better performance.
