Electrocatalysts for medium temperature PEM water electrolysis
Zlotorowicz, Agnieszka (Doctoral Theses at NTNU, 1503-8181; 2013:190, Doctoral thesis, 2013)The main subject of this PhD thesis is the fabrication and investigation the electrochemical behavior of anode catalysts appropriate for medium- temperature proton exchange membrane (PEM) water electrolysis (WE) operating ... -
Tailored Porosities of the Cathode Layer for Improved Polymer Electrolyte Fuel Cell Performance
Zlotorowicz, Agnieszka; Jayasayee, Kaushik; Dahl, Paul Inge; Thomassen, Magnus Skinlo; Kjelstrup, Signe (Journal article; Peer reviewed, 2015)We show experimentally for the fi rst time that the introduction of macro-pores in the nanoporous catalyst layer of a polymer electrolyte membrane fuel cell can improve its performance. We have ach- ieved a Pt utilization ... -
The Permselectivity and Water Transference Number of Ion Exchange Membranes in Reverse Electrodialysis
Zlotorowicz, Agnieszka; Strand, Robin Viktor; Burheim, Odne Stokke; Wilhelmsen, Øivind; Kjelstrup, Signe (Journal article; Peer reviewed, 2016)Reverse electrodialysis of saline solutions (RED) is a renewable energy technology with large potential. Key components in the system are the ion exchange membranes. This work evaluates the efficiency of commercially ... -
Zirconium hydrogen phosphate as an additive in electrocatalytic layers for the oxygen evolution reaction in PEM water electrolysis
Zlotorowicz, Agnieszka; Sunde, Svein; Seland, Frode (Journal article, 2015)For reasons of electrode integrity and durability it is desirable to add zirconium hydrogen phosphate to electrocatalytic layers in PEM water electrolysis. Common synthesis methods are frequently associated with an ...
