NOVELTY - An electrolyzer (310) has front platen (312), electrolyzer cells (330a,330b) and rear platen (336) arranged in series. Each electrolyzer cell applies electrical charge to electrolyte solution and separates hydrogen and oxygen gasses generated by applying electrical charge to electrolyte solution. Each electrolyte cell has channel gaskets (322a,322b) channeling flow of gas developed on anode-cathode plates (316,328), and gas flow media sheets (324a,324b) inserted on the cut-out portions of the channel gaskets. The anode-cathode plate (328) is connected to the electrical charge.    USE - Electrolyzer for energy storage device (claimed).    ADVANTAGE - Enables energy storage device to use hydrogen and oxygen gases to generate electricity as needed. Provides an electrolyzer that uses electricity with water in creating hydrogen and oxygen which are stored in tanks until needed. Enables output from the fuel cell to be fed to grid tie inverter for feeding to electrical grid as alternating current (AC) current or to be used to supply electricity directly to electrical device or system as desired. Provides a cost effective alternatives for converting the energy produced by wind turbines, water turbines, heat panels, and other energy sources into oxygen and hydrogen. Provides electrolyzer with unique design which provides cost effective for efficiently producing hydrogen and oxygen gases. Allows use of fairly common lower-cost materials in the electrolyzers without sacrificing efficiency or durability. The combination of high efficiency output and lower material costs allow the electrolyzers to be a very cost effective way of producing hydrogen and oxygen from water. Provides front platen with grooves which will contribute to the ease of manufacturing, repairing, and replacing parts in the electrolyzer.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an energy storage device.    DESCRIPTION OF DRAWING(S) - The drawing shows the exploded perspective view of the of the electrolyzer.
