Modeling the Environment-Dependent Kinetics of Oxygen Reduction Reaction – Effect of Relative Humidity
Autor: Masao Shibata, Adam Weber, Yu Morimoto, Iryna Zenyuk, Grace Anderson
Publikováno v: ECS Meeting Abstracts. :1367-1367
For proton exchange membrane fuel cells (PEMFCs) to achieve broad commercialization, the kinetics of oxygen reduction reaction (ORR) need to be better understood to improve the efficiency with minimized use of expensive Pt-based electrocatalyst(1). T

Publikováno v: ECS Meeting Abstracts. :1422-1422
For the widespread use of proton exchange membrane fuel cells (PEMFCs), cost reduction of the stack is indispensable. For this purpose, it is effective to reduce the use of Pt and other cell components by reducing the cell area with a high-power dens

Setting Development Targets for Fuel Cells and Systems for Heavy-Duty Trucks Using a Comprehensive Model-Based Approach
Autor: Takao Watanabe, Masao Shibata, Norihiro Fukaya, Tomoyuki Nagai, Takahisa Suzuki
Publikováno v: ECS Meeting Abstracts. :1468-1468
For a carbon-neutral society to be realized, widespread use of fuel cells for transportation applications would be effective. The widespread use of fuel cells, in turn, requires improvements in the durability and energy conversion efficiency when fue

Modeling Temperature-, Humidity-, and Material-Dependent Kinetics of the Oxygen Reduction Reaction
Autor: Masao Shibata, Masanori Inaba, Kazuma Shinozaki, Kensaku Kodama, Ryosuke Jinnouchi
Publikováno v: Journal of The Electrochemical Society. 169:044507
We propose a mathematical model that examines the temperature-, humidity-, and material-dependent oxygen reduction reaction (ORR) activity. We extended a conventional theoretical ORR micro-kinetic model by considering the temperature dependencies of

A Study on Power Cable Loads for a Floating Ocean Current Turbine
Autor: Masao Shibata, Ken Takagi
Publikováno v: Journal of the Japan Society of Naval Architects and Ocean Engineers. 20:99-108
This paper discusses power cable loads for a floating ocean current turbine. The floating ocean current turbine is supposed to have unique motion characteristics, which causes unknown loads to the power cable. In this study, two severe situations and
