    Abstract: The present invention provides a fuel cell separator with a gasket manufactured by integrally forming a gasket on one side of a separator; independently injection molding a frame gasket on a frame such that a first airtight portion covers the entire surface of the frame to maintain the shape of the frame gasket and a second airtight portion projects upward and downward from both ends of the first airtight portion; and bringing the first airtight portion of the frame gasket into contact with the other side of the separator with the gasket formed on one side thereof. To create a fuel cell stack in certain embodiments, the invention stacks the second airtight portion of the frame gasket on another second airtight portion of an adjacent unit cell with a membrane-electrode assembly interposed therebetween.

    Abstract: A diagnostic and heat management system for a fuel cell stack is provided herein that includes a diagnostic control analyzer that diagnoses and analyzes a state of the fuel cell stack by measuring a voltage and a current of the fuel cell stack. Also, an AC signal generator generates a diagnostic AC signal, and an AC component driving element that is included in an AC component in a current of the fuel cell stack. Additionally, a termoelement is driven as a heat absorbing device when a temperature of the AC component driving element is equal to or greater than a predetermined temperature and is driven as a heat emitting device when a temperature of the AC component driving element is less than a predetermined temperature, in order to manage heat generation in the AC component driving element.

    Abstract: A failure diagnosis apparatus that includes an alternating current (AC) absorption unit that is connected to the fuel cell stack and switched based on an applied AC signal to enable a current from the fuel cell stack to flow. In addition, an AC signal generator is configured to generate the AC signal and supply the generated AC signal to the AC absorption unit. As the current from the fuel cell stack is absorbed by the AC absorption unit based on an alternating signal, a stack current input into a diagnosis processing unit includes an AC component, thus the diagnosis processing unit may diagnose fuel cell stack failure by analyzing a frequency of the AC component.

    Abstract: A fuel cell system includes an air supply unit for supplying air containing oxygen to a fuel cell stack. A humidifier humidifies the supplied air. An air supply line is connected between a cathode inlet of the fuel cell stack and the humidifier to supply the humidified air to the fuel cell stack. A cathode-side exhaust line is connected between a cathode outlet of the fuel cell stack and the humidifier to supply a cathode exhaust gas discharged from a cathode of the fuel cell stack to the humidifier for humidification in the humidifier. A unified valve module includes a bypass line connected between the air supply line and the cathode-side exhaust line and an outward discharge port discharging the cathode exhaust gas to outside, and controls a gas flow between the humidifier and the fuel cell stack and between the bypass line and the outward discharge port.
