Abstract: An embodiment cell monitoring device for a fuel cell is provided. The cell monitoring device is mountable to a plurality of unit cells stacked in a first direction and includes a cell monitoring connector detachably connectable to a tab protruding from a side portion of a separator included in the unit cells in a second direction intersecting the first direction, a joint connector including a joint terminal guidable by a connection terminal to be inserted into the cell monitoring connector, and a controller disposed on a rear surface of the joint connector and directly connectable to a second end portion of the joint terminal opposite the first end portion to sense a voltage of each of the unit cells, the joint connector and the controller each being shaped to press a first end portion of the joint terminal toward the tab.

Abstract: In an embodiment a fuel cell includes a cell stack having a plurality of unit cells stacked in a first direction, first and second end plates disposed at both side ends of the cell stack respectively, the first and second end plates having a form in which a resin part envelopes a metallic insert and a sacrificial electrode disposed at the resin part of the second end plate adjacent to a cell having the highest potential among the unit cells.

Abstract: A fuel cell of the disclosure includes a cell stack including a plurality of unit cells stacked in a first direction, an end plate disposed on at least one of the two ends of the cell stack, a heating element disposed between the end plate and the cell stack, and a heater connector embedded in the end plate and electrically connected to the heating element. The end plate includes a core having a first rigidity and having a first recess defined therein to receive at least a portion of the heater connector, a reinforcement plate covering the first recess and having a second rigidity, and a clad having a third rigidity less than each of the first rigidity and the second rigidity and disposed so as to envelop the heater connector and to cover the core and the reinforcement plate.

Abstract: A fuel cell includes a cell stack having a plurality of unit cells stacked in a first direction, a plate disposed at at least one of two opposite ends of the cell stack, and a heating element disposed between the plate and the at least one of the two opposite ends of the cell stack. The heating element includes a plurality of heating patterns generating heat at different temperatures and the plate includes a plurality of power terminals connected to respective ones among the plurality of heating patterns.

Abstract: A fuel cell includes a cell stack including a plurality of unit cells stacked in a first direction, end plates respectively disposed at first and second end portions of the cell stack, each of the end plates including a core having first rigidity and a clad covering at least a portion of the core, the clad having second rigidity which is lower than the first rigidity, a heater plate provided with a heating element configured to generate heat in response to a driving power supply, the heater plate being disposed at at least one of positions between the end plates and the first and second end portions of the cell stack, and a connector accommodated in the core of each of the end plates and covered by the clad, the connector interconnecting the driving power supply and the heating element.
