Development of Pt-based and non-Pt-based electrocatalyst for fuel cells and batteries with high performance, durablity, and scalability is a strong social demand for the next-generation eco-friendly energy society[1].

In this meeting, we summarize our recent studies on i) development of a carbon nanotube (CNT)-based almost “immortal” fuel cell catalyst prepared by a double-polymer wrapping method [2], ii) pristine carbon nanotube/iron phthalocyanine hybrids with a well-defined nanostructure that show excellent efficiency and durability for oxygen reduction reaction[3], iii) decorating unoxidized-carbon nanotubes with homogeneous Ni-Co spinel nanocrystals that show superior performance for oxygen evolution/reduction reactions[4], and iv) a highly-durable CO-torelant poly(vinylphosphoric acid)-coated electrocatalysy supported on a nanoporous carbon[5].
