Use of Liquid Electrodes for Magnetohydrodynamic Power Generation Applications

The use of liquid electrodes in magnetohydrodynamic (MHD) power generation applications is proposed as a means of extending the lifetime of the electrodes in these systems.  Previous studies utilized various metals, metal alloys and ceramic materials as electrodes but all suffered from erosion processes in the harsh gas stream used in MHD power generation.  This invention describes a liquid electrode that can be used to achieve significantly longer life than a solid electrode as well as avoid fouling due to contamination.  Extending the life of the component improves the economic viability of the overall concept. Liquid walls can also be used in high-temperature heat exchangers.
