Abstract: A vehicular communication controller includes a microcontroller (MCU) located within a vehicle to generate, by a software component, a find service request to discover an offered service from one or more systems on a chip (SoC). The MCU may generate a service message packet that includes the find service request inserted into a payload of the find service message packet where the payload is bound to an automotive/embedded communication protocol. Using unicast or multicast, the find service message packet may be sent to one or more SoC receiving devices. The SoC receiving devices may deserialize the header and payload of the find service message packet to retrieve the find service request and generate a service directory message based on service metadata and publish a cloud event including a solicited response that is sent back to the software component.
Abstract: A fuel cell system includes a fuel cell generator, a rechargeable energy storage circuit, an auxiliary load, a converter circuit, and a switch circuit. The fuel cell generator is operable to generate electrical power in a stack output signal. The auxiliary load is powered by the rechargeable energy storage circuit while in a first mode, and powered by a local signal while in a second mode. The converter circuit is operable to convert the stack output signal into a plurality of recharge signals while in the first mode and in the second mode, and convert the stack output signal into the local signal while in the second mode. The switch circuit is operable switch the plurality of recharge signals to one or more electric vehicles, and switch the local signal to the auxiliary load while in the second mode.

Abstract: In various aspects, the present disclosure provides a method of manufacturing an electrode for an electrochemical cell. The method includes contacting a solid electrode material and a substrate at an interface. The method further includes preparing a liquid electrode material at the interface by heating at least a portion of the solid electrode material to a first temperature. The first temperature is greater than or equal to a melting point of the solid electrode material. The method further includes creating a layer of the liquid electrode material on the substrate by moving at least one of the solid electrode material and the substrate with respect to the other of the solid electrode material and the substrate. The method further includes forming the electrode by cooling the liquid electrode material to a second temperature. The second temperature is less than or equal to the melting point.

Abstract: A method, fuel cell system and vehicle for maintaining compression via re-compression is provided. By recovering fuel cell stacks of the fuel cell system after a pre-determined time of operation and performing re-compression on each of the recovered fuel cell stacks, power generation capacity, active area pressure and seal force is recovered to address increased contact resistance and loss of fuel cell system power generation capacity as well as decreased seal force and increased risk of reactant gas and coolant leak.
