Energy conversion cell for conversion of radiation and heat into electrical energy has metal negative electrode, graphite positive electrode and aqueous manganate and alkali metal hydroxide electrolyte

摘要

The metal negative electrode is especially made of tin (Sn). The positive electrode is made of graphite. The electrolyte consists of an aqueous solution of manganate (IV) salts and an alkali metal hydroxide especially potassium hydroxide. The electrolyte is heated, and electrochemical reactions take place as a current flows through an external load. Return reactions also take place in the electrolyte.
