Abstract:
1. A system for combinatorially screening an array of electrochemical cells, the system comprising: an electrolyte common to each of the cells of the array; an anode common to each of the cells of the array, and an anode catalyst library positioned between the anode and the electrolyte such that the anode catalyst library defines the individual electrochemical cells of the electrochemical cell array; a cathode common to each of the cells of the array, and a common cathode catalyst layer positioned between the cathode and the electrolyte; a common reservoir for supplying a second electrochemically reactive species to at least a portion of the common cathode catalyst layer; and an electrochemical probe configured to address each of the cells of the array individually, and to supply a first electrochemically reactive species to the individual members of the anode catalyst library; wherein each of the cells of the array are in a non-active condition with the exception of the cell that is receiving the electrochemically reactive species from the probe; and wherein the electrochemical probe is mounted to an X-Y motion stage controlled by a computer, and the system is monitored by a data acquisition system for collecting and analyzing the results of a test.
