Номер: WO2021059206A1
Автор: Bamidele O. FAYEMI, Steven Y. Yu, Tyler S. MATTHEWS
Принадлежит: 3M INNOVATIVE PROPERTIES COMPANY

A system includes an electrochemical cell pack. The electrochemical cell pack includes a housing having an interior space; a plurality of electrochemical cells disposed within the interior space; and a thermal management fluid disposed within the interior space such that the electrochemical cell is in thermal communication with the thermal management fluid. The system further includes a vent assembly comprising a flow control mechanism and a filter assembly disposed downstream of the flow control mechanism. The flow control mechanism is configured to enable fluid communication between the interior space of the housing and the filter assembly upon a condition within the interior space exceeding a predetermined threshold value. The filter assembly comprises an absorbent or adsorbent filter configured to remove one or more fluorine containing toxic components from a fluid stream passing through the vent assembly.
