  • 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: 10800272
    Abstract: A ground pad module for charging a power-driven vehicle is designed to be arranged on an underground accessible to the vehicle. The ground pad module includes a fan unit arranged within the ground pad module and configured to cool at least one electrical and/or electronic assembly arranged within the ground pad module by an air flow that can be supplied to the ground pad module from an exterior area. An inlet channel of the air flow is designed such that if the ground pad module is arranged as intended, water penetrating through an inlet opening of the inlet channel must overcome at least one step in a component of a flow direction of the water before it reaches the fan unit and/or the assembly with the component facing a direction opposite to the force of gravity.
