Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

Abstract: An electronic device includes a connector including a pair of terminals connected to a power source, a voltage sensor provided to detect a voltage between the pair of terminals, a communication device provided to perform communication with an external control device through a network, and a controller configured to determine whether the connector is separated from the power source based on a voltage variation between the pair of terminals, control the communication device to request the external control device to cut off power of the power source when the connector is separated from the power source, and control to perform self-discharge.
