Erratum: On the Performance of Proton Exchange Membrane Fuel Cells with a Catalyst Layer Fabricated Using an Inorganic Dispersant with Various Ultrasonic Mixing (ACS Omega (2022) 7:25 (21370-21377) DOI: 10.1021/acsomega.1c05777)

In section 3.1, the first sentence should read “Through ultrasonic mixing, an increasingly even distribution of platinum increases the probability of contact with hydrogen, which increases the ECSA45”, with the added ref 45 as follows: (45) Pollet, B. G. The use of ultrasound for the fabrication of fuel cell materials. Int. J. Hydrogen Energy 2010, 35 (21), 11986-12004 10.1016/j.ijhydene.2010.08.021. In the first paragraph of section 3.5, add the citation of ref 46 after the sentence “Samples that underwent longer high frequency vibrations generally perform better than samples that underwent low-frequency vibrations.46”
