description	The process for the precise determination of the surface area of an electrically conducting shaped body is performed by immersing said body as one electrode in an electrolyte. A steady or variable voltage or a steady or variable electrical current is applied to said electrode externally or internally to the electrochemical cell or is variated or is repeated once or indefinitely or is switched off. The diffusion processes which develop in the steady state or the unsteady state and which occur near to said electrode are monitored. The surface area of the electrically conducting shaped body is calculated by measuring the electrical current or the voltage or the transition time.
