Show morePolymeric ion exchange membranes are integral components of electrochemical conversion/storage devices such as fuel cells, water electrolyzers, and redox flow batteries. There has been dramatic progress in the research and development of cation exchange membranes (CEM). Nafion® (perfluorosulfonic acid membranes) is one example of a state-of-the-art CEM and has been successfully demonstrated in various electrochemical energy devices. Unlike CEMs, anion exchange membranes (AEMs) have been of limited utility to date due to their drawbacks, including poor chemical/mechanical stability and low ionic conductivity. However, alkaline environments result in better activity for electrochemical reactions and afford the possibility of using non-platinum group metal (PGM) electrocatalysts. AEMs, therefore, are still being studied in order to resolve existing challenges in terms of conductivity and stability in alkaline media and in strongly oxidizing solutions. In this work, AEMs derived from different types of polymer backbones were prepared, and their chemical stability and electrochemical property were investigated. Polysulfone (PSF) AEMs were prepared by first chloromethylating polysulfone, then by functionalizing chloromethylated polysulfone (CMPSF) with different base reagents. PSF-trimethylamine (TMA) AEMs showed a 40-fold reduction in vanadium (IV) ion (VO2+) permeability when compared to a Nafion® membrane and exceptional oxidative stability after exposure to a 1.5 M vanadium (V) ion (VO2 +) solution for 90 days. PSF-TMA AEMs were successfully demonstrated in the all-vanadium redox flow battery. Excellent energy efficiencies (>75 %) were attained and sustained over 75 chargedischarge cycles for a vanadium redox flow battery prepared using the PSF-TMA separator. Crosslinking of poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) AEMs using diamine was tried with intentions to improve the mechanical stability and electrochemical property of PPO AEM. Crosslinked PPO AEMs (30 ± 4 % at 25 oC) showed less liquid water uptake than non-crosslinked PPO AEMs (46 ± 5% at 25 oC) while maintaining comparable ionic conductivities (hydroxide ion conductivity of 45 mS/cm at 60 oC). Crosslinked PPO AEMs maintained mechanical integrity and still showed some mechanical stability (ultimate tensile strength of 3~4 MPa and elongation at break of 13~17 %) after exposure to 1 M KOH at 60 oC for 14 days, while noncrosslinked PPO AEMs completely lost their mechanical durability. Finally, this dissertation presents research related to perfluorinated AEMs prepared using a Grignard reagent. These membranes exhibited 0.7 mmol/g of Cl- ion exchange capacity (IEC), 20 mS/cm of hydroxide ion conductivity at 20 oC, and 10 % of water uptake at room temperature. The membranes also maintained 90 % of their initial conductivity after an exposure to 1.5 M VO2+ in 3 M H2SO4 solution for seven days.

Show moreThe IPRO team was successful in designing a process that converts biomass into liquid fuels for transportation. The biomass chosen was cow manure because of two main reasons. The abundance of cows in southern Wisconsin provides an ideal place for the process to be built. Also, because most other types of potential biomasses currently have uses, manure was favorable. The process was split into three sections: gasification, gas clean-up and Fischer-Tropsch (FT) reactor.

Show moreThis semester, the IPRO 310 team is continuing the work started by the previous semester’s team. Our work will build off of the previous team’s work and many of our objectives will be an extension of their original objectives. This semester, the team has set forth the following objectives: Finish benchmark testing on the lawnmower including gas emissions Further research the safe storing and usage of hydrogen as a fuel Develop guidelines to create and maintain a safe laboratory area Investigate avenues to decrease overall conversion cost Perform the engine conversion Write a step-by-step conversion manual keeping in mind safety and Occupational Safety and Health Administration (OSHA) standards Although the team’s main objective is to provide a safe way to convert a gas-powered lawnmower to a hydrogen-power lawnmower, the team will strive to create an environment in which team collaboration, the application engineering knowledge and ability, and individual passion for the project can flourish thus providing a rewarding and educational experience for all of the participants.
