Abstract:	Microbe-based hydrogen production is a potentially cost-effective, non-polluting approach to the production of hydrogen. Research efforts are underway to identify, isolate, and enhance microbial strains which facilitate direct sunlight-to-hydrogen conversion. These efforts are hampered by a lack of adequate instruments to rapidly detect and pinpoint hydrogen producers. There is a need for assays which provide sufficient sensitivity, short response times, scalability, and compatibility with high-throughput methodologies to allow for rapid screening of microbe colonies. GVD Corporation is assisting the National Renewable Energy Laboratory (NREL) in the development of a multilayer chemochromic sensor that will identify hydrogen producing microbes. GVD’s proprietary solvent-free polytetrafluoroethylene (PTFE) coatings allow H2 gas to reach the sensor’s catalyst layer but prevent atmospheric contaminants from doing so. PTFE-coated assay plates survive the warm, wet conditions of multi-month testing and are able to pinpoint hydrogen-producing organisms exactly as intended. Later improvements to the manufacturing process will allow the technology to be adapted to other sensor markets, most notably safety sensors for fuel cell applications
