Abstract
A method and apparatus are described for removing a chemical product species produced by electrochemical action at an electrode or by a chemical reaction which occurs at the surface of a solid catalyst. The method involves providing a flow of a host solution generally parallel to a surface at which a chemical reaction occurs. The flow of the host solution causes the products from the chemical reaction to be entrained in a thin boundary layer which moves along the surface. These products can be removed from a cell by withdrawing the boundary layer from the cell as it reaches the trailing edge of the surface.
