The first system developed was the 64 channel pin electrode array, using liquid electrolyte. The developed method improved both the quality and reproducibility of the data and has been used to rank catalyst samples, as well as to optimize loadings and the preparative methods of inks.

The results from the two high-throughput methods are compared to those of the single channel systems. The mass and specific activities towards reduction of oxygen were studied using a series of Pt/C and PtCo/C catalysts.
