A constant phase element (CPE) is an equivalent electrical circuit component that models the behavior of a double layer, which is a kind of imperfect capacitors. In general, it is known that the exponent α at CPE depends on surface roughness, surface distribution of capacitance, and adsorbed ions. Nanoporous electrodes have been attracting much attention for diverse applications such as energy conversion devices and sensors. When CPE concept is applied to model the behavior of the electrical double layer at nanoporous electrodes, it is sensitively subject to the roughness, pore shape, and dimension of the nanopores. In this presentation, it is shown that mass transfer along the nanopores affects the CPE, which is significantly different from that of flat electrodes.
