... density, indicating an improved electrocatalytic surface with faster charge–discharge reactions at anode and cathode and low overvoltage. Electrochemical impedance studies on the coated and uncoated surface clearly showed that the polarization resistance and impedance were decreased by Ni–Co or N–Co–Fe...

... at an inclination angle, θ , of 90 deg than at θ = 0 deg or 180 deg , where it experienced a sudden power breakdown at the rated operating point. The output voltage and internal impedance of each cell in the module were specifically monitored over a long-term operation. Measurements were made of the temperature...
