Scientists have developed a method of examining the processes of a fuel cell, by producing the first three dimensional images of the interior or a fuel cell. Similar to Magnetic Resonance Imaging (MRI) used for viewing inside the human body, this technique developed by researchers from the Northwestern University and led by Professor Scott Barnet, uses a dual-beam focused-ion beam microscope that provides resolution showing nanometer-scale features. With the "MRI" for Fuel cells, processes inside fuel cells can be examined, understood, and ultimately, improved.
One application of this technique is observing and maintaining quality. With this application, fuel cells may be checked right after production. This would minimize the occurrence of faulty fuel cells and ensure that fuel cell users benefit from safe and effective renewable power sources. Read more about this story here.
