Abstract
Gas flow through electrodes for electrochemical cells having a porous flow through matrix with electrocatalysts supported on the surfaces of the matrix within the pores, the pores providing a through route for a metastable colloid of electrochemically reducible or oxidizable gas bubbles in liquid electrolyte, with absorption of some of the gaseous component on the walls of the pores. Improved depolarization of the electrode provides long life and stable gas flow through electrodes for electrochemical cells.
