I think PEMFCs are very, very cool, as is the huge amount of research going on around them right now. Basically, they use hydrogen as fuel, which means that the exhaust from electricity production is all water and heat. Since they’re fairly lightweight, they’d be great candidates for use in vehicles.
As with any neat emerging technology, there are tonnes of avenues for research going on simultaneously. Right now, Bazylak’s group is using the CLS to investigate how water pathways in different parts (specifically the gas diffusion and microporous layers) of the PEMFCs affect function.
Dr. Bazylak doesn’t appear in any of the photos, just the students in her research group. They were wildly goofy and so much fun — note the mysterious blue liquid known as Gatorade making an appearance in this photoset.
