NREL CCM Deposition Study

These data describes multiple low-temperature electrolysis experiments where specified current densities were held for 180 s to determine the corresponding voltage. At each step, an impedance measurement was taken. Each of these experiments used Pt catalyst on the anode and cathode. The difference between each dataset is the deposition method of the catalyst onto the membrane. Within each dataset, a low to high current hold was performed multiple times in order to investigate the durability
