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： A fuel cell generation system control apparatus performs a method for controlling power of a fuel cell generation system. A monitoring device monitors power of the one or more fuel cell modules. A controller compensates for power of one or more first fuel cell modules by one or more second fuel cell modules, based on the monitored power, and performs power control of the one or more fuel cell modules. The fuel cell generation system control apparatus addresses a problem in which power of the fuel cell generation system is reduced as there is a change in external environment or an increase in driving time upon power control of a multi-module fuel cell system.

摘要： An electrolyte membrane of a membrane-electrode assembly is formed by a manufacturing method yielding a membrane with improved chemical durability. The manufacturing method includes preparing an antioxidant solution, mixing the antioxidant solution and a first ionomer dispersion solution, drying the mixture to produce a composite having an antioxidant and a first ionomer surrounding the antioxidant, introducing and mixing the composite with a second ionomer dispersion solution, and applying that mixture to a substrate and drying the mixture to manufacture an electrolyte membrane. The resulting electrolyte membrane includes the composite having an antioxidant in an ionic state and a first ionomer surrounding the antioxidant.
