Research

Justin investigated novel cathode architectures using a new manufacturing technique for PEM fuel cells. The technique is known as Reactive Spray Deposition Technology (RSDT) and uses an open atmosphere flame based process for platinum catalyst production and a set of secondary spray jets for carbon and Nafion® deposition. Decoupling of the catalyst formation from the carbon support and proton conductor materials allows for real-time control of cathode composition. Combinations of a bi-layer cathode consisting of a platinum only sub-layer were investigated along with a composite layer.

First job after graduation:

Technical Officer, National Research Council Institute for Fuel Cell Innovation. Justin is continuing his work on RSDT development of cathode layers for PEM applications at the NRC-IFCI.
