TECHNOLOGY LICENSING OPPORTUNITY: Hydrogen Contamination Detector

Read the official notice on SAM.gov

Summary from the notice

This invention by scientists at Los Alamos National Laboratory (LANL) introduces a new type of real-time hydrogen fuel contamination detector that can sense tiny amounts of harmful contaminants before they reach a fuel-cell vehicle. It works by using a special membrane that keeps itself properly hydrated using an internal water reservoir, allowing it to stay sensitive even when measuring completely dry hydrogen—a major challenge for existing sensors. Even small amounts of impurities can permanently damage a fuel-cell car’s power system, and today’s testing methods are slow, expensive, and often done only after problems occur. By enabling continuous, in-line monitoring at hydrogen fueling stations, this technology helps ensure that hydrogen is clean and safe, supporting the growth of a reliable and consumer-friendly hydrogen economy. The Challenge: As hydrogen becomes a mainstream clean fuel, even tiny impurities—like CO, H?S, or excess moisture—can permanently damage the sensitive fuel-cell systems that power vehicles and equipment. Yet today, hydrogen quality is typically verified using expensive, lab-based instruments that require expert operators and provide results only after the fact. This delay means a single contaminated batch can affect many vehicles before anyone realizes there’s a problem. Traditional sensor concepts have failed because they require adding moisture to the hydrogen stream, which interferes with detecting water contamination and violates emerging fuel…
