Comparing with the massive efforts in developing innovative catalyst materials system and technologies, structural design of cells has attracted less attention on road toward high-performance electrochemical CO2 reduction reaction (eCO2RR). Herein, a hybrid gas diffusion electrode-based cell is proposed using highly porous carbon paper (CP) graphene aerogels (GAs), which expected to offer direc...

A comprehensive mathematical model of the performance of the cathode-supported solid oxide fuel cell (SOFC) with syngas fuel is presented. The model couples the intricate interdependency between the ionic conduction, electronic conduction, gas transport, the electrochemical reaction processes in the functional layers and on the electrode/electrolyte interfaces, methane steam reforming (MSR) and...

The molten carbonate fuel cell (MCFC) has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis (MCEC), it provides a promising option for producing fuel gases such as hydrogen, via water electrolysis, and syngas, via co-electrolysis of water and carbon dioxide. The molten carbonate cell can thereby operate reversibly as a dual energy converter for...

The diffusion coefficient of isopropanol in alkaline medium using electrochemical methods on Pd electrode has been studied by linear sweep voltammetry (LSV) with different sweep rate and chronoamperometry in 1.0 M KOH solution containing 1.0 M isopropanol. Isopropanol oxidation on the Pd electrode is an irreversible charge-transport process and controlled by a diffusion process. The diffusion c...
