Continuous flow electrochemical cell and process
A continuous electrolyte flow electrochemical cell having an outer tubular shaped electrode, a central electron conducting current collector shaft extending through the central portion of the tubular electrode, the current collector shaft having projecting radially therefrom a plurality of electron conducting extensions spaced to permit flow of liquid electrolyte therethrough forming a counterelectrode. In a preferred embodiment the outer tubular electrode is separated from the inner counterelectrode by a concentric tubular shaped separator permitting separated flow of two electrolytes therethrough, one through the annular electrolyte space between the separator and the electrode, and a second through the tubular counterelectrode chamber within the separator. The invention provides a high efficiency, continuous electrolyte flow electrochemical cell particularly well suited for use in heterogeneous electrochemical reaction processes, such as coal depolarized water electrolysis. In one embodiment, the counterelectrode may be rotated by attachment of a rotating means to the current collector shaft.
