An energy storage cell includes a cylindrical pressure vessel, a porous ceramic coating on the interior surface of the pressure vessel, a plurality of insulating stripes of an electrically insulating polymeric coating on the interior surface of the porous ceramic coating, and a plurality of catalytic stripes of a catalytic material overlying the plurality of insulating stripes. The insulating material is preferably a polymer such as polytetrafluoroethylene. The catalytic material catalyzes the chemical combination of hydrogen and oxygen, and is preferably a mixture of platinum powder, polytetrafluoroethylene, and methocel. The insulating stripes and catalytic stripes lie around the circumference of the cylindrical pressure vessel and extend parallel to the cylindrical axis of the cylindrical pressure vessel. The energy storage cell further includes a plate stack having a plurality of plate sets within the wall of the pressure vessel, with the plate sets lying perpendicular to the cylindrical axis. Each plate set includes a positive electrode, a negative electrode, and a separator between the positive electrode and the negative electrode. The separator contacts the porous ceramic coating between the stripes of the electrically insulating coating. There are, additionally, a screen between each plate set, an electrolyte within the pressure vessel, and a pair of electrical leads extending from the plate stack and through an electrical feedthrough in the wall of the pressure vessel to an exterior of the pressure vessel.
