Björn Wickman

Forskarassistent vid Chalmers, Fysik, Kemisk fysik

Min forskning finns i fälten elektrokatalys, fotoelektrokemi och ytreaktioner for miljö- och hållbara energitillämpningar. Arbetet omfattar studier av elektroder och katalysatormaterial för lågtemperaturbränsleceller (PEMFC), fotoelektrokemisk vätgasproduktion och elektrolys för att tillverka förnybara bränslen samt projekt för vattenrening. Genom att designa välkontrollerade modellsystem i kombination med kraftfulla karakteriseringstekniker så kan man öka kunskapen om en rad viktiga elektrokemiska system.
