It was recently determined that the masking allowed leakage of catalyst precursor solution into the rest of the cell area, so the true active area is more accurately calculated as the whole cell geometric area not covered by seal. SP [ sp 1 SP ] sp For easier comparison with similar work, the values have been recalculated in accordance with this corrected active area.
