  • Patent number: 10818943
    Abstract: A fuel cell system includes: a turbine including a changing mechanism that adjusts a pressure difference between an upstream pressure and a downstream pressure of the turbine, the turbine recovering at least a part of energy of the cathode off-gas using the pressure difference and assisting driving of the motor with the recovered energy; and a control unit configured to drive the changing mechanism to increase or decrease the recovered energy. The control unit acquires a correlation temperature correlated with a temperature of the cathode off-gas discharged from the turbine and performs freezing avoidance control of not setting the degree of opening to be equal to or less than a predetermined degree of opening when the correlation temperature is lower than a predetermined threshold temperature at which the turbine is able to become frozen.

  • Patent number: 10727525
    Abstract: A lithium ion battery including a core-shell structured fire extinguishing particle is disclosed. When the battery is overheated to a predetermined temperature, a shell of the fire extinguishing particle coated on one surface or both surfaces of a porous separator is melted, a fire extinguishing material disposed in an inner space of the shell is released into an electrolytic solution of the battery, and as a result, it is possible to prevent the battery from being ignited or exploded even though the battery is overheated. Further, the melted shell clogs pores of the porous separator to block lithium ions from moving, such that the battery is blocked from being driven, thereby preventing the battery from being overheated any more.
