  • Patent number: 11152627
    Abstract: The invention relates to a bipolar plate for a fuel cell, comprising an anode plate with anode gas channels and a cathode plate with cathode gas channels, said plates having an active region and supply regions and being arranged one over the other such that the gas channels form coolant channels. The aim of the invention is to improve such a bipolar plate such that the flow conditions of reactants and coolant in the bipolar plate are optimized. This is achieved in that the height and/or the width of the cathode gas channels increase(s) from a first side of the active region to a second side of the active region, and the height and/or the width of the anode gas channels decrease(s) from the first side of the active region to the second side of the active region, wherein the cross-sectional area and/or the hydraulic diameter of the cathode gas channels increases, and the cross-sectional area and/or the hydraulic diameter of the anode gas channels decreases.

  • Patent number: 10882492
    Abstract: A method for authenticating a user on a transportation vehicle, wherein the transportation vehicle is coupled to an external device storing an authentication secret code and to at least one token storing a token secret code. In the method the token secret code is transmitted to the transportation vehicle when an operator control action performed with the at least one token is sensed. A new secret code is generated from the token secret code and is compared with the authentication secret code. When the new secret code matches the authentication secret code, the user is authenticated on the transportation vehicle. Also disclosed is an apparatus for authenticating a user on a transportation vehicle.
