Development of an advanced modeling platform for assessing chemical and mechanicalmembrane durability in polymer electrolyte membrane fuel cells - Year Two

Hydrogen powered polymer electrolyte membrane fuel cells (PEMFCs) are a clean energy technology that generates electricity without harmful emissions at the point of use. To accelerate commercialization, current R&D efforts mainly target reduced cost and increased lifetime. The proposed research project addresses both aspects by developing a unified chemical and mechanical modeling platform for evaluating membrane durability in PEMFCs. The core validation is based on extensive test and field data provided by our industry partner, Ballard Power Systems.

Radio Acoustical Virtual Environment: from Lab to Field

Verbal communication in noise while wearing hearing protection devices (HPDs) is often difficult. Recently, a “Radio Acoustical Environment” (RAVE) was developed within the EERS-ETS Industrial Research Chair in In-Ear Technologies (CRITIAS) to enhance communication for people wearing HPDs in noise. With RAVE, speech is captured from inside the ear, denoised, and enhanced to be sent only to listeners within a given spatial range. This range is determined based on the changes in the talker’s vocal effort and background noise level. Currently, RAVE is at its prototype stage.

Study of Ultra-High By-Pass Ratio turboengine integration and noise reduction with Large Eddy Simulations.

Jet noise is still the main contributor in airplane noise at take-off, which has been shown to induce health problems in the residents near airports that are now embedded in most large cities such as Toronto or Montreal. Engine manufacturers are now considering the Ultra-High Bypass Ratio (UHBR) type engine to further reduce noise. Yet the UHBR is a large shrouded fan configuration, having strong interactions with wings while integrated into the airframe.

Theoretical investigation of Asphaltene/Wax precipitation and deposition from crude oil: Study involving Nucleation kinetics and Bulk/Interfacial properties

The pipeline transport sector is facing the issue of precipitation of unwanted heavy molecular compounds namely asphaltene and wax eventually leading to deposit along the inner walls of the pipeline. This consumes a lot of energy and maintenance cost. The objective of this work is to provide a solution to inhibit the precipitation of these compounds by theoretically investigating the root cause of the problem. The present study focuses on investigation at both molecular scale level involving Nucleation kinetics and macroscopic level by studying bulk/interfacial properties of the system.

Large-Area High-Performance Transparent Electrodes for Pen/Touch Sensor Research

Transparent electrodes (TEs) combine high optical transparency and electrical conductivity, useful in different devices such as light-emitting diodes, displays and solar cells. A highly competitive market of electronic devices, such as phones and flexible touch screens as well as a worldwide increasing demand for energy, drives research to improve the performance of TEs. However, mass production of high-performance TEs is expensive due to costly materials and fabrication techniques.
