摘要： The present disclosure relates to an electrolyte membrane for fuel cells having improved chemical durability and a method of manufacturing the same. Specifically, the method includes preparing a polymer film, depositing catalyst metal on one surface or opposite surfaces of the polymer film to obtain a reinforcement layer, and impregnating the reinforcement layer with an ionomer to obtain an electrolyte membrane.

摘要： The present disclosure relates to a method of manufacturing an electrolyte membrane for fuel cells capable of effectively removing hydrogen and/or air crossing over. Specifically, the method includes coating a slurry including at least an ionomer on a substrate to manufacture an ion transfer layer, manufacturing a laminate including the substrate and the ion transfer layer, and providing a pair of laminates to form an electrolyte membrane, wherein the ion transfer layer has a catalyst region formed at one side thereof based on a width-direction center line thereof, the catalyst region including a catalyst.

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.

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.
