Voltammetric probing of pH at carbon nanofiber–Nafion™–carbon nanofiber membrane electrode assemblies

Electrochimica Acta, 2012
Abstract Methods are developed for using a carbon nanofiber membrane electrode assembly (cnMEA) for three-electrode electrochemical measurements in unsupported liquid or gaseous media. The carbon nanofiber membrane (ca. 20 μm thickness) is hot-pressed from both sides onto a Nafion™ ion conductor film (ca. 50 μm thickness).
