Research summary

To combat climate change, we need to reduce carbon emissions—even in hard-to-decarbonize areas, such as the energy, transportation and industrial sectors. Electrochemical energy conversion devices offer a promising way to achieve this because they can effectively convert fuel into on-demand power, produce hydrogen from liquid water and electricity, and even convert carbon dioxide emissions into useful forms of fuel. But their high cost is a barrier to their widespread adoption.

Dr. Keonhag Lee , Canada Research Chair in Energy Systems Innovation, is trying to advance the performance and durability of these devices. He and his research team are developing methods to create nanostructured electrodes and designing better support layers. They are also creating a system to directly observe how fluids and gases move at the electrode-electrolyte interface. Their work will help to mitigate climate change by accelerating the development and scale-up of electrochemical energy conversion systems.
