Paper Abstract

In this paper, the authors discuss the chemical process of fabricating IPMCs and their variations suitable for applications of fuel cells, electrolysis, and hydrogen sensors. The underlying principle of fabrication of IPMCs is an initial stage of molecular metallization and subsequent surface plating. Characterization results including TEM photographs and physical properties are provided. It has been found that the molecular metallization process is slow due to the complex phenomena related to an increased mass transfer resistance as platinum precipitate and possibly slow kinetics involved in. TEM photographs confirmed 'the cluster-network model' that is convenient to describe mass transfer phenomena within the IPMC.
