    摘要： The present invention provides an apparatus for effectively preventing carbon corrosion from occurring at the cathode of a fuel cell. The present apparatuses include an air blower supplying air from an air supply source to a fuel cell; a fuel cell receiving air from the air blower to generate electricity by a chemical reaction; an air discharge pipe through which residual air remaining after oxygen of the air is consumed for chemical reaction in the fuel cell is discharged; a pressure sensor provided in the air discharge pipe for detecting air pressure in the fuel cell; an air discharge solenoid valve provided in the air discharge pipe for controlling air flow of the air discharge pipe; and a controller controlling operation of the air blower and the air discharge solenoid valve by receiving a signal detected by the pressure sensor wherein the controller detects the air pressure through the pressure sensor to allow the air blower to supply air to the fuel cell until the air pressure reaches a predetermined pressure and then closes the air discharge solenoid valve until the oxygen in the fuel cell is completely exhausted, thereby preventing the formation of hydrogen/oxygen interface at the anode of the fuel cell.

    摘要： The present invention provides a sealing structure of a sealing portion for maintaining the airtightness of a coolant passage in two stacked separators of a fuel cell, wherein a groove in which an adhesive is to be filled is formed on a surface of one of two separators, and dam portions are formed on both sides of the groove to prevent the adhesive applied in the groove from overflowing into a connection passage and a coolant passage. Accordingly, the adhesive overflowing from the groove when the two separators are bonded to each other by applying a pressure is collected in the dam portions to form three sealing lines, thus improving the airtightness of the sealing portion. Moreover, it is possible to solve the problem that the performance of the fuel cell stack is deteriorated when an antifreeze/coolant leaks from the coolant passage to an MEA, in which the fuel cell reaction takes place, or the leaking coolant contaminates a catalyst of the MEA.

    摘要翻译： 本发明提供了一种密封部分的密封结构，用于保持燃料电池的两个层叠的隔板中的冷却剂通道的气密性，其中在两个分离器之一的表面上形成有要填充粘合剂的槽， 并且在槽的两侧形成有坝部分，以防止施加在槽中的粘合剂溢出到连接通道和冷却剂通道中。 因此，当通过施加压力将两个分离器彼此接合时，从槽中溢出的粘合剂被收集在坝部中以形成三条密封线，从而提高密封部的气密性。 此外，可以解决当防冻剂/冷却剂从冷却剂通道泄漏到发生燃料电池反应的MEA时，燃料电池堆的性能劣化的问题，或泄漏的冷却剂污染催化剂 MEA。
