The structure and heat dissipation of aluminum reduction cell was introduced. The heat dissipating capacity of medial part was calculated, and the heat flux and temperature were tested for the feasibility study of thermoelectric generation. The thermoelectric generator was designed and processed based on the requirements for the structure of aluminum reduction cell and thermoelectric generation. It was tested on the aluminum reduction cell. The output power and generation efficiency was calculated. The results show that the application is feasible. A new energy saving method of aluminum electrolysis was explored.
