  • Patent number: 10826083
    Abstract: In solid polymer electrolyte fuel cell stacks, increasing the height of support features in the transition regions and/or increasing the depth of the transition regions improves the flow of reactants therein and thus improves the sharing of flow in the channels in the reactant flow fields. The support feature height and transition region depth are increased so as to be out of plane with respect to the landings and channels in the reactant flow fields. The invention is suitable for cells employing metal flow field plates or plates in which no adhesives are employed in the transition regions.

  • Patent number: 10756324
    Abstract: The positive electrode substrate exposed portions or the negative electrode substrate exposed portions, or both, of an electrode assembly is split into two groups, and therebetween is disposed an intermediate member made of a resin material and holding one or more connecting conductive members. Collector members for the substrate exposed portions split into two groups is electrically joined by a resistance welding method to the substrate exposed portions split into two groups, together with the connecting conductive member(s) of the intermediate member. The resin material portion of the intermediate member protrudes, in the extension direction of the substrate exposed portions split into two groups, beyond the ends of the substrate exposed portions split into two groups and the ends of the collector member to a prismatic outer can. This structure enables enhanced resistance between the substrate exposed portions and the collector member and curbs variation in the welding strength.

  • Patent number: 10752515
    Abstract: The present invention describes a lithium-substituted magnesium ferrite material based hydroelectric cell and process for preparation thereof. A novel galvanic cell process of generating electric current in distilled water by lithium substituted magnesium ferrite hydroelectric cell has been developed. A synthesis process of ferrite pellet having zinc anode and silver inert electrode has been developed. The material splits water molecules and conducts ions within porous ferrite. Split ions electrochemically react with electrodes and form zinc hydroxide at anode and hydrogen gas at silver electrode. This hydroelectric cell has generated 5 mA short circuit current and 950 mV open cell voltage. Current increased to 20 mA by thermally deposited Zn electrode on a ferrite pellet. The cell is very economical and highly sensitive towards electrolysis of water molecules. It is a green source for producing energy and has a potential to excel from existing electrochemical batteries.

  • Patent number: 10516147
    Abstract: Implementations of a battery pack with reduced magnetic field emission are provided. In some implementations, the battery pack may be configured to reduce and/or eliminate the magnetic field normally generated while electrical current is being drawn from one or more cylindrical-steel electrochemical cells (e.g., AA batteries) by a connected electrical device. In some implementations, each electrochemical cell of a battery pack may include a conductive sleeve comprised of four conductive strips that are separated from the electrochemical cell by a thin insulating layer of material. In this way, the conductive sleeve provides a return path for electrical current that minimizes the loop area between the electrochemical cell and the conductive sleeve thereof. In some implementations, the four conductive strips of a conductive sleeve may be equally spaced 90 degrees apart and/or positioned longitudinally on a cylindrical-steel electrochemical cell, separated therefrom by the insulating layer of material.
