This paper from the group of Matthias Arenz at the Nano-Science Center at the University of Copenhagen may prove crucial for comparing catalysts and catalyst matrices for low temperature fuel cells.
In “Pt based PEMFC catalysts prepared from colloidal particle suspensions – a toolbox for model studies” Speder and co-workers demonstrate the applicability of their approach to catalyst fabrication in a model study. The key result is that their catalyst synthesis allow for accurate comparison of different catalyst systems as their procedures are reproducible and yield consistent results.
Fuel cell catalysts on solid supports have been difficult to compare, as the means of their preparation introduce differences, often larger than those variations resulting from the parameter under study. The work summarized in this paper opens a way around this issue, making comparative study feasible. Of this reason alone you should have a look at the paper. On top of that you get the interesting result regarding the anchoring of Pt catalyst particles to the carbon support.
