Dr. St-Pierre is a leading electrochemical engineer with over 15
years academic and industrial research experience within the
electrochemical technology industry, including energy conversion,
electrowinning, electrodeposition and electrosynthesis. He has a
track record of mathematical modeling, concept generation and
patenting, and, management of technical demonstration and
development partnerships, including program development, with
academic, government and industrial organizations. Dr. St-Pierre is
currently expanding and summarizing his experience in a fuel cell
engineering textbook for undergraduate and graduate students.
Dr. St-Pierre's current research interests include the development
of diagnostic methods for proton exchange membrane fuel cells to
facilitate fundamental understanding of two key issues: water
management and performance degradation. For water management,
residence time distribution and micro-fluidics were selected to
respectively measure the amount of water in flow field channels, gas
diffusion electrodes and membranes during cell operation, and the
fundamental properties (saturation, capillary pressure, intrinsic
and relative permeabilities) associated with two-phase flow in thin
porous media (gas diffusion electrodes). The information generated
will be used to validate and further develop mathematical models
with the objective to increase prediction accuracy. For performance
degradation, the development of methods to non-destructively
characterize and accelerate catalyst particle sintering at low
temperatures (< 100 ºC) represent the main objectives.
