A membrane electrode assembly (MEA) for hydrogen fuel cells has been fabricated using single-walled carbon nanotubes (SWCNTs) support and platinum catalyst. Films of SWCNTs and commercial platinum (Pt) black were sequentially cast on a carbon fiber electrode (CFE) using a simple electrophoretic deposition procedure. Scanning electron microscopy and Raman(More)
An automated whole cell biosensor system was developed by integration of immobilized microbial cells in a flow-through system with screen-printed flow-through electrodes as detectors. The detectors used were thick-film Pt-electrodes in a 3-electrode configuration constructed as sandwich flow-through cells with a volume of about 36 microliters polarized at(More)
