摘要： Disclosed are a catalyst complex and a method of manufacturing the same. The catalyst complex may be manufactured by uniformly depositing metal catalyst particles on pretreated support particles through an atomic layer deposition process using a fluidized-bed reactor, which may be then uniformly dispersed throughout the ionomer solution. As such, manufacturing costs may be reduced due to the use of a small amount of metal catalyst particles and the durability of an electrolyte membrane and OCV may increase. Further disclosed are a method of manufacturing the catalyst complex, an electrolyte membrane including the catalyst complex, and a method of manufacturing the electrolyte membrane.

摘要： The present disclosure relates to a composite electrolyte membrane and a method of manufacturing the same. A catalyst composite layer in the composite electrolyte membrane uniformly includes a catalyst and an antioxidant, whereby it is possible to inhibit generation of hydrogen peroxide by side reaction. In addition, the catalyst composite layer is formed as a separate layer, whereby the catalyst composite layer is instead degraded, greatly inhibiting membrane degradation even in the case in which radicals attack an ionomer due to small side reaction. Furthermore, it is possible to control the position of the catalyst composite layer including the catalyst and the antioxidant by adjusting the thicknesses of a second ion exchange layer and the catalyst composite layer, whereby it is possible to protect a specific degradation position, and therefore it is possible to efficiently improve membrane durability.

摘要： A startup limitation method for a fuel cell vehicle. In particular, a sensor is used to determine whether or not a hydrogen inlet door of the fuel cell vehicle is opened. When the hydrogen inlet door is opened, shutting down the fuel cell vehicle. A pressure of a hydrogen storage tank of the fuel cell vehicle is measured, and in response, the fuel cell vehicle is shut down when an increase of the pressure of the hydrogen storage tank of the fuel cell vehicle exceeds a predetermined pressure variation range if the fuel cell vehicle has not already been shut down due to the hydrogen inlet door of the fuel cell vehicle being opened.
