A microfluidic electrochemical cell with integrated PdH reference electrode for high current experiments
Fanavoll, Espen Vinge; Harrington, David A.; Sunde, Svein; Singh, Gurvinder; Seland, Frode (Journal article; Peer reviewed, 2016)An on-chip thin-film palladium hydride reference electrode is described for use with microfluidic electrochemical cells. A Pd electrode fabricated by photolithographic methods is charged with hydrogen in-situ with a simple ... -
Generator-Sensor Impedance at Double Channel Electrodes
Holm, Thomas; Ingdal, Mats; Strobl, Jonathan R; Fanavoll, Espen Vinge; Sunde, Svein; Seland, Frode; Harrington, David A. (Journal article; Peer reviewed, 2017)A method for measuring downstream concentration effects through electrochemical impedance spectroscopy at double channel electrodes is demonstrated. An ac current perturbation is applied at an upstream working electrode ... -
Mass-transport impedance at channel electrodes: Accurate and approximate solutions
Holm, Thomas; Ingdal, Mats; Fanavoll, Espen Vinge; Sunde, Svein; Seland, Frode; Harrington, David A. (Journal article; Peer reviewed, 2016)Accurate numerical electrochemical impedance spectra at channel electrodes are obtained using commercial finite element method software. These agree with experimental measurements on the hexaammineruthenium(II/III) reversible ... -
