    Abstract: The present techniques provide electrochemical devices having enhanced electrodes (46) with surfaces that facilitate operation, such as by formatio n of a porous nickel layer on an operative surface, particularly of the cathode (50 ). The porous metal layer increases the surface area of the electrode (46), which m ay result in increasing the efficiency of the electrochemical devices. The formation o f the porous metal layer is performed in situ, that is, after the assembly of the electrodes (46) into an electrochemical device. The in situ process offers a number of advantages, including the ability to protect the porous metal layer on the electrode surface from damage during assembly of the electrochemical device. The enhanced electrode (46) and the method for its processing may be used in any number o f electrochemical devices, and is particularly well suited for electrodes in a n electrolyzer (100) useful for splitting water (12) into hydrogen (14) and oxygen (16).
