Carbon Nano-Fibre Supported Electrocatalysts for Fuel Cells
Briskeby, Stein Trygve (Doktoravhandlinger ved NTNU, 1503-8181; 2012:294, Doctoral thesis, 2012)This thesis covers topics related to fuel cell electrocatalyst preparation and electrochemical characterization. In particular, the influence of catalyst support material for Pt catalysts is examined in detail. The aim is ... -
Preparation of electrocatalysts by reduction of precursors with sodium citrate
Briskeby, Stein Trygve; Tsypkin, Mikhail; Tunold, Reidar; Sunde, Svein (Journal article; Peer reviewed, 2014)In this work synthesis of Pt/C catalysts by reduction of H2PtCl6 with sodium citrate has been investigated. The strong pH-dependence of citrate as a reducing and stabilizing agent has been explored, and an optimum pH range ... -
Stability of carbon nanofibre-supported platinum catalysts in the presence of chloride under controlled mass-transfer conditions
Briskeby, Stein Trygve; Tsypkin, Mikhail; Tunold, Reidar; Sunde, Svein (Journal article, 2014)The effect of chloride on the stability of platinum electrocatalysts was studied by rotating disk measurements in sulfuric acid electrolyte with a continuously increasing concentration of chloride anions. The activity ...
