A fuel contamination detection system includes a fuel quality analyzer, a multiway valve, and a controller. The multiway valve includes a first inlet, a second inlet, and an outlet. The multiway valve also may include a switching device. The controller is electrically coupled to the analyzer. The controller may be coupled to the switching device, if present. Fuel is flowed through the fuel quality analyzer and an output current is measured to determine whether the fuel includes impurities. The controller is operable to signal a fuel dispensing system to dispense fuel if the fuel is sufficiently clean or cease dispensing fuel if the fuel is impure.

System and method for detection of impurities during refueling

A fuel quality analyzer for detecting contaminants in a fuel supply includes an anode flow field plate defining a first fuel flow field channel and a fuel inlet port, a cathode flow field plate defining a second fuel flow field channel and a fuel outlet port, a polymer electrolyte membrane between the anode and cathode flow field plates, a first electrode between the anode flow field plate and the polymer electrolyte membrane, and a second electrode between the cathode flow field plate and the polymer electrolyte membrane. The second electrode has a higher platinum loading than the first electrode. A reservoir volume is defined by the anode and cathode flow field plates. At least a portion of the polymer electrolyte membrane extends into the reservoir volume. The reservoir volume is configured to retain water to humidify the polymer electrolyte membrane.

Neutron multiplicity detector control logic and firmware may control a neutron multiplicity detector such that higher count rates can be achieved by an order of magnitude of more over conventional control logic and firmware. Count rates of over 1,000,000 cps, and even over 1,500,000 cps, have been realized in some implementations.
