Definitions
- Loss of working medium to the atmosphere will also be a problem if a leak should develop suddenly or over time during operation of a closed loop system. Since the cooling system should operate continually and undisturbed over the operational lifetime of the electrolysis cell, any leak may easily accumulate to loss of larger amount of (expensive) cooling/working media (like Helium and others) and thereby increase the cost of system operation.
- Rg. 2 discloses a second embodiment for energy recovery from one cell
