The present invention provides an electrochemical apparatus (300a) comprising an electrolytic cell (100) for producing an electrolysis product (50, 60) and a reaction vessel (200) for consuming at least some of the electrolysis product (50, 60) as a reagent in an exothermic chemical reaction. The electrolytic cell (100) comprises an electrochemical device, itself comprising an electrode (10) and a conduit (20). The electrode (10), which is configured as an electrode (10, 70) of the electrolytic cell (100), has a first part for immersion in an electrolyte, a second part for making electrical contact with a current-carrying conductor, and a third part between the first and second parts for making thermal contact with a heat transfer fluid (HTF). The conduit (20) is arranged to bring the heat transfer fluid (HTF) into thermal contact with the third part of the electrode (10). The electrode (10) is made of carbon, which has reduced electrical resistivity and thermal conductivity at temperatures above ambient. Therefore, if the third part of the electrode (10) is heated by means of the HTF, its electrical resistivity and thermal conductivity are reduced. The former enables more efficient flow of electrical current between the first and second parts of the electrode and therefore reduces the total internal resistance of the electrolytic cell (100). The latter reduces the flow of heat between the first and second parts of the electrode (10) and therefore helps to prevent heat loss from the electrolytic cell (100) via the electrode (10) to the current-carrying conductor. Both effects make the electrolytic cell (100) more energy efficient. The apparatus (300a) further comprises a product transfer pathway (110) arranged to transfer the electrolysis product (50, 60) from the electrolytic cell (100) to the reaction vessel (200), and a first heat exchanger (210) arranged to transfer heat (Q) from the reaction vessel (200) to the heat transfer fluid (HTF) in the conduit (20). The electrochemical device may therefore be used to inject waste heat from the exothermic chemical reaction into the electrolytic cell (100). This reduces the electrical power consumption of the electrolytic cell and also makes the combination of the electrolytic cell (100) with the exothermic chemical reaction supplying the heat (Q) more energy efficient overall. The invention also provides methods of operating such an electrochemical apparatus. The invention is particularly suited to producing Group 1 and Group 2 metals by electrolysis with increased energy efficiency.
