Combinatorial investigation of Pt–Ru–M as anode electrocatalyst for direct methanol fuel cell

Combinatorial screening of thin film electrocatalysts for a direct methanol fuel cell anode

“…Combinatorial libraries have been fabricated via a variety of methods, including physical vapor deposition techniques such as sputtering [18,19], or less commonly by techniques such as electro-deposition [20] or gel transfer [21]. Such libraries have been characterized by many different screening techniques including fluorescence imaging [22][23][24], scanning electrochemical microscopy [25], multiarray half cell [26] and multiarray fuel cell [27]. There are benefits and disadvantages with each method [28], with the criteria that define the optimum combinatorial method [29] for a particular materials problem still the subject of discussion.…”

Combinatorial screening of fuel cell cathode catalyst compositions

“…Comparing catalysts requires a method that carefully considers the many combinations and permutations of variables [35]. Combinatorial catalyst investigations have had some success in this respect, with screening of samples being performed by a variety of techniques including fluorescence imaging [36][37][38][39][40], scanning electrochemical microscope [41][42][43][44][45], rotating disk electrode [46][47][48][49][50][51], multi-array half cell [52][53][54] and multi-array fuel cell [32,55]. In all of these investigations, the primary experimental approach was to vary composition while striving to keep the other variables constant.…”

Effect of fluorine–oxygen mixed gas treated graphite fibers on electrochemical behaviors of platinum–ruthenium nanoparticles toward methanol oxidation

“…During the last decade there have been extensive efforts in the research of the catalysts for an electrochemical oxidation of methanol and the development of the direct methanol fuel cells (DMFCs) [1][2][3][4][5]. Direct injection of the methanol fuel would avoid the problems that are related to the production, purification and storage of hydrogen.…”
