Latest Patents

One of Dunlop's latest patents is for a metal-hydrogen battery. This rechargeable battery operates on the back-to-back electrode placement theory, which differs from traditional single metal oxide-hydrogen couple cells. The design includes interconnecting electrodes in series and constructing an electrode stack of series-connected electrodes to achieve high voltage operation. In another embodiment, back-to-back construction is utilized for positive electrodes in a parallel arrangement to complete an operative cell. The individual cells are separated by a nonporous polymer separator, which prevents the formation of electrolyte films that can lead to electrochemical shorts. The entire stack is held under compression by end plates and tie rods, ensuring durability and efficiency.

Another notable patent is for a lanthanum nickel hydride-hydrogen/metal oxide cell. This sealed electric fuel cell utilizes a reoxidizable compound as the positive electrode and a hexagonal nickel-rare earth metal hydride as the negative electrode. The energy released from the electrochemical oxidation-reduction reaction of the anode is converted into electrical energy, demonstrating Dunlop's innovative approach to fuel cell technology.
