Understanding the nanoscale processes that control corrosion initiation and propagation in bulk materials is a critical area of research. With Protochips’ machine-vision powered suite of in-situ TEM tools you can utilize the electron microscope as a real-time laboratory to study the underlying mechanisms that control corrosion initiation and propagation.

Electrochemical aging confirms migration and coalescence within a fuel cell. Migration and coalescence are key mechanisms in the degradation of fuel cells. In this experiment a solution of Pt3C0/C and .1M HClO4 is prepared within the electrochemical cell of the Poseidon Select Electrochemistry. The cell was then inserted into the electron microscope for imaging. While imaging the cell, the sample was exposed to a cyclic pattern of electrical stimuli, from -.5V to 1V. Coalescence is observed to correspond to changes in the electrical stimuli of the experiment.
