Abstract: Hydrogen generation systems and processes are described that facilitate on-board generation of hydrogen for use in internal combustion engines. A hydrogen generator converts diesel exhaust fluid (DEF) or other urea-based fluids into a hydrogen-rich product gas. In some embodiments waste heat from the engine is used to preheat the DEF for the hydrogen generator. Steam reformers, electrolyzers and fuel reformers that generate hydrogen using the DEF are described.

Abstract: A fuel cell system bipolar plate formed of a graphite metal composite. The bipolar plate is formed of a metal foil formed of tantalum or a metal having a tantalum coating. Flexible graphite deposited in rows on each surface of the metal foil forms channels of the bipolar plate and providing a flow field. The graphite metal composite provides flexural strength as well as resistance to corrosion.

Abstract: Provided in the present disclosure is a method for measuring alkalinity of water sample, including following steps: step 1: constructing a mathematical model correlating the alkalinity of a water body with a water body electrical signal variation value; step 2: bringing a water sample into contact with an acidic material to cause a change in a water sample electrical signal value, collecting the water sample electrical signal value before and after the water sample is brought into contact with the acidic material, and constructing a water sample electrical signal variation value; and step 3: deriving the alkalinity of the water sample by substituting the water sample electrical signal variation value into the water body electrical signal variation value in the mathematical model. The above method does not involve using titrant and prior calibration operation, which does not require high-level hardware equipment.

Abstract: A portable fuel cell system that is compact. The integration of a snorkel into the chassis allows the fuel cell to operate inside a backpack. The fuel cell system includes a thermal management system to keep the surface of the chassis at a comfortable temperature for the user. A boiler is mounted on a side of the fuel cell stack such that waste heat from the fuel cell stack is efficiently transferred to the boiler to vaporize fuel. A burner is positioned away from the fuel cell stack so that the system can be more compact. A thermal management system, including a blower, a heatsink, and a cooling air shroud, regulates the temperature of the fuel cell system.

Abstract: A fuselage heat exchanger having channels for dissipating waste heat generated by fuel cells that power unmanned aerial vehicles (UAVs) or drones. A heat exchanger built into the fuselage can dissipate such waste heat. Coolant flowing through channels embedded within an aircraft fuselage panel dissipates heat to airflow around the outer surface of the fuselage.

Abstract: A heat and chemical resistant sealant for fuel cells that includes a fluoroelastomer sealant and a fluoroplastic gasket. The fluoroelastomer sealant is dispensed around a perimeter of a top surface of a bipolar plate. The compliant sealant conforms to surface imperfections of the bipolar plate. A fluoroplastic gasket is positioned over the fluoroelastomer sealant and bipolar plate. When compressed, the combination of the fluoroelastomer sealant and fluoroplastic gasket provide a reliable seal that can withstand the high operating temperatures of fuel cells.

Abstract: A fuel cell power system that includes multiple strings that each have multiple sub-stacks of fuel cells. Each sub-stack is electrically isolated from other sub-stacks and each sub-stack can be independently controlled by a DC control module on a printed circuit board. The DC control module of a sub-stack can regulate or shut off the output power of the sub-stack if the sub-stack becomes weak or fails. A sub-stack can be shut off while other sub-stacks in the system continue to operate. The output power of other sub-stacks can be increased to compensate for sub-stacks that are shut down.

Abstract: Filtration systems and methods for purifying windshield washer fluid to yield methanol pure enough for fueling methanol fuel cell systems. Pumping commercially available windshield washer fluid through filtration systems having one or more filters can remove additives from the windshield washer fluid. The filtration systems include filters, such as activated carbon filters, nanofiltration filters, reverse osmosis filters, and ion exchange resin filters.

Abstract: Conductive, elastic ionic polymers with high tensile strength (iono-elastomers) resulting from amphiphilic polymers capable of self-assembly into micellar hierarchical gel-like structures in an electrically conductive liquid are provided. The micellar hierarchical gel-like structures engage in micellar corona cross-linking to form the iono-elastomers. The iono-elastomer exhibits high stretchability and displays increased electrical conductivity upon mechanical stretching. A method for producing iono-elastomers includes mixing amphiphilic polymers in a conductive liquid to form micellar hierarchical gel-like structures, and cross-linking the micellar coronas. Devices incorporating iono-elastomers and methods for creating such devices are also provided. The devices incorporating the iono-elastomers may be wearable.
