Novel ACNT arrays based MEA structure-nano-Pt loaded ACNT/Nafion/ACNT for fuel cell applications.

A novel designed free-standing, sandwich-structured membrane electrode assembly (MEA), nano-Pt loaded (0.142 mg cm(-2)) ACNT/Nafion/ACNT via the attachment of two sets of aligned CNT array electrode structures to opposite sides of a Nafion PEM membrane exhibits significantly improved performance compared to commercially available Pt/CB catalysts used in PEM fuel cell applications.
