Title: Hydrogen fuel quality analyzer with self-humidifying electrochemical cell and methods of testing fuel quality

Abstract

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.
