Development of Membrane Integrated Electrode for Improving Current Efficiency

Manufacturing industry accounts for 28.4% of domestic greenhouse gas emissions, a higher proportion than major countries. Therefore, it is necessary to reduce greenhouse gas emissions for manufacturing industries in order to realize carbon neutrality across the country. Standards of greenhouse gas reduction for each manufacturing industry require appropriate carbon neutralization technology depending on energy consumption characteristics by industry sector. Representatively, the wet plating process requires high power consumption, and most of the applied current is not directly used for plating reactions, but is used for side reactions such as water electrolysis and secondary compound formation. Low current efficiency due to these factors ultimately leads to high carbon emissions and causes problems with higher greenhouse gas emissions. To solve these problems, a membrane-electrode integrated module can be utilized to suppress the production of side reactants, improve plating efficiency and reduce carbon emissions. In this study, an experiment was conducted on a membrane-integrated electrode material to improve the current efficiency of the plating process. In detail, electrode performance evaluation was conducted to select the optimal composition according to various metal combinations and crystal forms.
