  • Patent number: 11302939
    Abstract: A direct liquid fuel cell power generation device comprises a direct liquid fuel cell system and a low-temperature auxiliary starting component. A heat exchanger is arranged at a stack cathode inlet. The heat of a fuel solution at a stack anode outlet is used to heat the air. The heat generated by an electronic load for starting is used to heat a condenser. The heat of a methanol solution at a liquid outlet of a gas-liquid separator is used to preheat high-concentration fuel flowing into a refueling pump. Starting and operation in a low-temperature environment can be realized through auxiliary heating of external power supplies such as the low-temperature auxiliary starting component or an in-vehicle cigarette lighter. Organic micromolecule substances such as methanol and ethanol are used as fuel and are subjected to catalytic combustion in a catalytic combustor.

  • Patent number: 11302995
    Abstract: The present disclosure provides a buffering member and a battery module, the buffering member comprises a first member and a second member. The first member comprises a first main body and a first connecting portion, the second member comprises a second main body and a second connecting portion. The first main body and the second main body face each other, and the first connecting portion is cooperated with and fixedly connected to the second connecting portion. Because the first member and the second member are independent members, and they can be formed by separately cutting a sheet. Because the first member and the second member each are small in size and simple in structure, and they can be rapidly formed by using less material, the whole structure of the buffering member is simple and the buffering member uses less material, thereby maximally improving the utilization rate of the sheet.
