Abstract: A fuel cell is described that uses a movable overpressure prevention unit to automatically narrow the fluid flow path when internal pressure exceeds a safe limit. The system includes a cell stack for power generation, a fluid supply unit, and conduits directing air, hydrogen, or coolant to the stack. An overpressure prevention member is biased by an elastic element so it remains out of the flow under normal conditions. At higher pressure, it moves into the path, limiting the cross-sectional area and lowering pressure. A variant employs an extension bracket between separate conduits, replacing a standard hose bracket while integrating the same protective mechanism. Additionally, a method is disclosed in which an extension bracket with an overpressure prevention member helps prevent damage to components by automatically engaging when fluid pressure surpasses a set threshold.

Abstract: A fuel cell stack includes a cell stack including a plurality of unit cells stacked in a first direction, an end plate disposed at at least one of first end portion and second end portion of the cell stack, an enclosure disposed with the end plate to surround a side portion of the cell stack and configured to be divided into a plurality of segments, a first gasket disposed in a first gap defined between the plurality of segments, and a second gasket disposed in a second gap defined between the enclosure and the end plate. The first gasket includes an end portion facing the second gasket in the first direction, and the end portion of the first gasket presses against the second gasket based on the end plate and the enclosure being assembled in the first direction.

Abstract: Provided is a gas cooker. When foods are cooked using a top burner, inclinations of main flame holes defined in the top burner are different according to positions of the main flame holes to prevent textile disposed adjacent to a front end of a top plate from burning. Thus, a user may further safely cook the foods.

Abstract: A top burner and a cooker having the top burner are provided. The top burner includes a first burner provided with a plurality of flame holes that form flame by combusting mixed gas and a second burner provided with a plurality of flame holes that form flame separated from the flame formed by the flame holes of the first burner by combusting the mixed gas. An arrangement of the flame holes of the first burner is realized in a different shape from an arrangement of the flame holes of the second burner.

Abstract: Provided is an oven range. A communication opening which is formed at a front end of a bottom surface of an oven chamber is selectively opened or closed by an opening/closing member linked to the rotation of an oven door for opening or closing the oven chamber. Accordingly, the oven range is advantageous as it uniformly cooks a food and simultaneously prevents a burner from being contaminated.

Abstract: A cooking device is provided. The cooking device includes a cavity and a burner. The cavity provides a cooking chamber. The burner is at the cooking chamber in the cavity and heats food in the cooking chamber. The burner includes a supply part and a combustion unit. A gaseous fuel mixed with air flows in the supply part. The combustion unit is connected to the supply part to receive the mixed gaseous fuel and to burn the received mixed gaseous fuel flowing within the combustion unit. The combustion unit has a single loop shape.

The burner includes a supply part and a combustion part. The supply part supplies a gaseous fuel mixed with air. The combustion part burns the mixed gaseous fuel and has an open curve shape.

Abstract: A gas cooker is provided. First and second front burners are disposed on the left and the right of a front upper surface of a top plate at an interval in a row. Lower ignition parts of the first and second front burners are disposed at a distance from an imaginary straight line passing through central points of the first and second front burners in parallel with the front end of the top plate, toward a front end of the top plate.
