      Fuel cells are clean and efficient power generation systems using air and variety of fuel cells. Nowadays, intermediate temperature operation solid oxide fuel cells (IT-SOFCs) and polymer electrolyte fuel cells (PEFCs) are actively developed. However, conventional IT-SOFC does not meet market demand well so far. Also, improvement of performance and stability of conventional PEFC devices is required now.

          In order to design the ‘state-of-the-art’ IT-SOFC with the quality of exceeding limits of conventional IT-SOFC and develop the high quality PEFC device which has good balance between high performance and its stability, the design of interfaces in fuel cell devices is key challenge. In our work, we try to fabricate the active interfaces in fuel cell devices along the guide of modelling ( surface and bulk lattice statics calculations and surface first-principles calculation ) based on microanalysis data. If our model is reasonable, we believe that our interface of electrolyte/ electrode in the devices will show us improved property. Then we can move on advanced step using interactive combination among sophisticated fabrication, operando microanalysis, and advanced modelling. In the last phase of our project, we will see radical innovation in energy and environmental field ( i.e. GREEN innovation). That is our challenge in fuel cell science and technology field.

          In this challenge, we have great opportunity to input really new data to big database. Eventually, the combination work of artificial intelligence ( AI ) and big database will start new type deep learning process using our new input data. We foresee that the proposed optimized material development concept will accelerate the R & D of next generation fuel cell devices to see the GREEN innovation in our society.
