Fundamental research in physical chemistry, catalysis, and interface science

Platinum particles on porous carbon supports used to catalyze both hydrogen oxidation at the anode and oxygen reduction at the cathode in PEMFC. Currently the most effective catalyst but prohibitively expensive for commercialization.

A key electrochemical reaction in hydrogen fuel cells where oxygen gains electrons. It is a notoriously sluggish process that requires efficient catalysts.
