Despite the great potential of electrochemical energy devices (fuel cells, electrolyzers, rechargeable metal-air batteries, etc.), the high cost, lowperformance, and poor durability of the catalyst-coated electrodes under the operating conditions have precluded their overall efficiency.

In most electrochemical energy devices (EEDs), approximately 70-80% cost is contributed from the catalyst-supported electrode part alone. Therefore, to bring the EEDs to the competitive level of conventional energy technologies (internal combustion engines), it is necessary to reduce the cost of catalyst-coated electrodes with increased efficiency/durability. Thus, the ultimate goal of this research group is to address these issues and to provide pollution-free energy by developing next-generation high-performance materials and their utilization in the fabrication of the device. The impact of the activities will be directly on the economic and technological progress along with the fundamental understanding of the electrochemical processes.

Focus areas:

• Fundamental electrochemistry and mechanistic studies
• High-performance electrocatalytic materials development
• Electrode designing for the various catalytic process (ORR, OER, HER, CO2RR, N2RR, etc.)
• Fabrication of next-generation electrochemical energy devices (fuel cells, water electrolyzers, flexible supercapacitors, etc.)
