Abstract
Fuel cell gas sensors using an aperture in a fuel cell gas sensor that allows for determination of a gas proportion in a sample that includes more gas than could otherwise be safely sampled. The aperture is adjustable between an open and a closed state. The amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the amount of time that the aperture is in the open state. Alternatively, the amount of the gas of interest exposed to the fuel cell may be adjusted by adjusting the size of the aperture.
