Summary
Servicenews article - The Clarity Fuel Cell vehicle has two very different cooling systems. One system cools the fuel cell system; the other one cools the inverter system. The fuel cell system uses a 50% coolant mixture called fuel cell insulating fluid, This fluid can't be mixed with any other fluid. Doing so cuts its insulating properties and will damage the fuel cell system.
