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.
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 talkers vocal effort and background noise level. Currently, RAVE is at its prototype stage.
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.
Etalim is a Canadian high technology company developing a breakthrough heat engine generating electricity from any fuel or heat source. The Etalim TAC (Thermal Acoustic Converter) is a unique technology that converts any high temperature gradient to electricity, with high efficiency (20%-30%) and simplicity. The TAC represents a unique class of device that combines principles of thermodynamics, high-amplitude acoustics, mechanical resonance and materials science in a unique way.
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.
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.

The objective of the project is to develop an automated monitoring system to accurately and reliably detect deterioration within gearboxes operating on an industrial forming line. This will involve reviewing, developing and testing one or more methodologies based on vibration signal measurement and analysis. In particular the work will focus on exploring existing potential methods, defining the capabilities of different sensors that could be used in the given environment and developing appropriate vibration signal analysis algorithms for gearbox deterioration detection and decision making.
