Method for the optimization of fuel supply comprising a carbonyl compound to the catalytic electrode of a fuel cell

摘要

The method involves defining reference voltage for a cell when fed with fuel exempt from a polluting agent. A threshold voltage corresponding to a preset operating voltage of the cell is defined. A calibration curve for given operating conditions is defined, where the curve allows a parameter corresponding to a flow rate to be defined. An amount of the polluting agent is detected to define another parameter corresponding to content of the agent present in fuel. A maximum stoichiometry coefficient is defined for a fuel stream under the conditions, depending on the parameters. The curve relates the threshold voltage to the flow rate. The agent is a carbonyl-containing polluting agent such as carbon monoxide agent.
