Fuel crossover, experimental determination

Gas-Phase Fuel Crossover In the case of gas-phase reactants, there are several methods to determine reactant crossover. The most commonly used are the (1) bubble gauge, (2) the OCV decay test, and (3) the limiting current test. The bubble gauge and OCV decay test can be easily performed and are the most convenient approaches, while the limiting current test requires some additional experimental complexity and can be a little unreliable.
