A detailed description of a method using a self-pressurized autoclave to run aqueous electrochemical experiments at temperatures above the normal boiling point of water is given. Relevant challenges with studying electrochemical reactions at high current densities in such systems are identified, and potential methods for solving these challenges are provided. The method is demonstrated for a three-electrode setup in sulfuric acid electrolyte up to 140°C.
