The Lab is making a research of improving performance of fuel cells using platinum-supported graphene. The outline and the schema by Associate Professor Uemura are as follows. Making the best structure of the catalyst layer where hydrogen and oxygen react to realize higher performance and lower cost of fuel cells. &nbsp; Conventional catalyst layers have 10\u03bcm-thick porous structures where platinum-supported carbon nanoparticles are covered with polymers (ionomer). &nbsp; Hydrogen ions (protons) will be carried by ionomers to the surface of platinum when generating electricity, however, the performance of generation will decrease because ionomers will be a factor to impede transportation of oxygen. &nbsp; Then, our research group has started research and development of a brand new catalyst layer structure to decrease impedance of transportation of oxygen using platinum-supported graphene. &nbsp; In the experiments we are planning to form porous structures utilizing characteristics of nanofibers to improve performance of fuel cells. &nbsp; William\u00a0Smith\u00a0Clark\u00a0(U.S.) Botanist\u00a0and\u00a0Agronomist Invited\u00a0to\u00a0Sapporo\u00a0Agricultural\u00a0School\u00a0(currently Sapporo\u00a0National\u00a0University)\u00a0in\u00a01876\u00a0and\u00a0taught students\u00a0natural\u00a0science.
