Electrochemical redox refrigeration device
Stanford researchers have made an electrochemical redox refrigeration device that provides high cooling power densities without the environmental liabilities of hydrofluorocarbon refrigerants. The device resembles a liquid version of a Peltier cooler, but with 10x larger entropy change per carrier compared to state-of-the-art thermoelectric materials. This ultra small-scale device can easily be combined with existing liquid-based cooling systems, and potentially take the place of solid-state thermoelectric coolers.
