METHOD OF REMOVING CONTAMINANT FROM FUEL CELL ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a method of removing contaminants such as carbon monoxide from the anode or the cathode of a fuel cell.

SOLUTION: A method of optimizing a waveform of an electrical current applied to an electrode includes the steps of: applying an electrical current to an electrode; determining a waveform of the voltage or the current of the electrical current; representing the waveform by a mathematical description such as an analytical function characterized by a number of unknown coefficients and a fixed number of known functions; measuring a function of a device associated with the application of the electrical current; feeding the waveform description and the measurements to an algorithm including an optimization routine which uses the points or coefficients as independent variables for optimizing the function of the device; and performing a calculation to determine values of the points or coefficients which optimize the function of the device, and thereby determining an optimized waveform of the electrical current to be applied to the electrode of the device.
