  • Publication number: 20250075354
    Abstract: A bipolar plate for an electrochemical system, such as an electrolyzer, having a separator plate and a support element firmly connected to the separator plate. The separator plate comprises a through-opening as an inlet or outlet for a fluid, a fluid guiding structure with a plurality of protrusions arranged at the through-opening for guiding the fluid between the plurality of protrusions, a bead arrangement which partially surrounds the through-opening, and a flow field with an electrochemically active region. The fluid guiding structure is arranged between the through-opening and the flow field such that the fluid can flow from the through-opening through the fluid guiding structure to the flow field or vice versa. The support element is configured to bridge the fluid guiding structure.

  • Patent number: 5941220
    Abstract: A motor vehicle has an internal combustion engine with an external exhaust gas recirculation system in the form of an exhaust gas return duct connecting an exhaust duct to an intake duct and the vehicle passenger compartment has a heater with a heat exchanger receiving a fluid heat transfer medium. At least part of the structure of the exhaust return duct has two walls, and heat transfer medium flows through the space formed between the walls, providing an exhaust return heat exchanger which transfers the heat removed from the returned exhaust gas to the heat transfer medium which provides the heater with additional heating power so that additional heater frequently required for heaters used with engines having a high degree of efficiency is not required for operation of the motor vehicle when outdoor temperatures are low. Also, nitrogen oxide emissions are reduced by lowering the maximum combustion temperature, and fuel consumption is reduced.
