Abstract
An apparatus () configured to determine reactant purity comprising: a first fuel cell () configured to generate electrical current from the electrochemical reaction between two reactants, having a first reactant inlet () configured to receive a test reactant comprising one of the two reactants from a first reactant source (); a second fuel cell () configured to generate electrical current from the electrochemical reaction between the two reactants, having a second reactant inlet () configured to receive the test reactant from a second reactant source (); a controller () configured to apply an electrical load to each fuel cell and determine an electrical output difference, OD, between an electrical output of the first fuel cell () and an electrical output of the second fuel cell (), and determine a difference between a predicted output difference and the determined electrical output difference, OD, the predicted output difference determined based on a historical output of difference and a historical rate of change in said output difference determined at an earlier time, said controller () configured to provide a purity output indicative of the test reactant purity at least based on the difference between the predicted and determined output difference.
