Correction to "On the Performance of Proton Exchange Membrane Fuel Cells with a Catalyst Layer Fabricated Using an Inorganic Dispersant with Various Ultrasonic Mixing".

[This corrects the article 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) .

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” Reference 46 is follows:

(46) .

In the last paragraph of the paper, add the citation of ref 47 after the sentence “In summary, the current proposed mixing method between carbon black and platinum using higher ultrasonic vibration frequency for fabricating the catalyst layer is potentially promising in the future due to its may possibly lower the manufacturing cost by much less use of the platinum that definitely requires further investigation47”, in which ref 47 is as follows:

(47) .
