Hydrogen fuel cell vehicles require specialized coolants with ultra-low electrical conductivity to prevent short circuits and ensure safe operation.
These coolants, often
ethylene glycol-based
, are formulated with specific additives to maintain low conductivity, protect fuel cell components from corrosion, and withstand extreme temperatures.
Here's a more detailed look:
-
Ultra-low Electrical Conductivity:. Opens in new tabFuel cell coolants must have significantly lower electrical conductivity than coolants used in internal combustion engines. Conductivity is measured in microsiemens per centimeter (µS/cm), and fuel cell coolants typically aim for conductivity below 5 µS/cm, according to Dober .
-
Corrosion Protection:. Opens in new tabFuel cell coolants need to protect various materials like stainless steel, titanium alloys, copper, and graphite from corrosion. This is achieved through specialized corrosion inhibitors, often non-ionic, formulated into the coolant.
-
Temperature Stability:. Opens in new tabFuel cell coolants must maintain their performance characteristics across a wide range of temperatures, from very low to high operating temperatures, especially in electric vehicles.
-
Specific Coolants:. Opens in new tabCompanies like InnoChill offer coolants like TF220A designed for fuel cells, while Arteco has developed Freecor® EV Micro 10 , and Liqui Moly offers Fuel Cell Coolant FCF20.
-
Material Compatibility:. Opens in new tabFuel cell coolants must be compatible with the materials used in the fuel cell stack, including the bipolar plates and other components.
-
Beyond Conductivity:. Opens in new tabWhile low conductivity is critical, other factors like frost and boiling protection, oxidation protection, and overall additive stability also play a role in the performance and longevity of fuel cell coolants.

Why does Elon Musk not believe in hydrogen fuel cells?
Musk has long been a vocal critic of hydrogen fuel cells, branding them as
inefficient compared to battery-electric solutions
. He has previously remarked that the use of hydrogen energy is “mind-bogglingly stupid,” arguing that it's a less efficient way to store and use energy compared to batteries.

What is needed for a hydrogen fuel cell?
A fuel cell is composed of
an anode, cathode, and an electrolyte membrane
. A typical fuel cell works by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. At the anode site, a catalyst splits the hydrogen molecules into electrons and protons.
