Recebido em 30/12/10; aceito em 15/4/11; publicado na web em 17/6/11 CONSTRUCTION OF A CELL-AUTOCLAVE FOR ELECTROCHEMICAL MEASUREMENTS AT HIGH TEMPERATURES. Measurements at high temperature using liquid solutions require special cells and materials which are able to support the temperature and pressure developed inside. The constructed cell was designed to support pressures up to 20 bar, temperatures relatively high up to around 200 o C, depending on the pressure developed inside the system. It

Then, it is supposed that this work represents a great contribution to the electrochemical studies of materials in solutions at high pressure and temperature.
