摘要:
Provided are a method for depositing a catalyst in a fuel cell, a fuel cell obtained by the method, and an apparatus for operating the fuel cell. The method for depositing a catalyst in a fuel cell includes: oxidizing a catalyst provided at the top of the cathode with air introduced to the cathode under the operating condition of the fuel cell; and depositing the oxidized catalyst gas at the reactive zone of the cathode. The method allows deposition of an activated catalyst ingredient at the cathode of a fuel cell by disposing a catalyst (such as Pt, Ag, Pd, Ru, etc.) highly reactive to reduction of oxygen at the side to which oxygen is introduced, and oxidizing and vaporizing the catalyst under an actual operating condition.
摘要:
The present invention relates to a method for measuring human intelligence using a neurobiogical model. The invention provides a method which enables neurometric IQ to be measured by processing the MRI and fMRI images of subjects to determine cortical thicknesses and brain activation levels, determining structural IQ (sIQ) and functional IQ (fIQ) from the cortical thicknesses and the brain activation levels, and using the structural IQ (sIQ) and the functional IQ (fIQ) as predictors to measure the neurometric IQ of the subject. According to the present invention, the concept of a neurometric IQ (nIQ) model is established and can assist in easily assessing individual differences in general cognitive ability. These results suggest that general cognitive ability can be explained by two different neural bases or traits: facilitation of neural circuits and accumulation of crystallized knowledge.
