P1.9.6 Capacitive Gas-bubble Sensor for Solid Oxide Fuel Cell

A. Kobayashi, H. Hiraoka & M. Yamaguchi
Solid oxide fuel cell (SOFC) is a type of hydrogen fuel cell for home use. A problem with SOFC is that carbon dioxide (CO2) accompanies the hydrogen, when this is generated from natural gas by fuel reforming. In this study, we propose a gas-bubble sensor which is used in a battery-cell to prevent damage. The gas-bubble sensor has two detection electrodes wound around the outside of a cylindrical plastic housing. By measuring the changes in...
