Investigation Of Oxygen Reduction Reaction In Carbon-Based Electrocatalysts, Andrew Mason
Investigation Of Oxygen Reduction Reaction In Carbon-Based Electrocatalysts, Andrew Mason
Honors Theses
In the modern era, some global challenges are energy storage conversion. To find sustainable solutions to this problem, researchers have turned to renewable energy resources. An example of promising energy generation devices is fuel cell. Fuel cells are electrochemical systems that convert the chemical energy of the fuel to electrochemical potential that can be used as direct current (dc) generators. Although these technologies are very attractive, they are known to be expensive due to high cost of catalysts and concerns regarding their energy densities. Fuel cells composed of two electrodes, namely cathode and anode and electrolyte separating the oxidizing agents …

Thermotoga maritima is an anaerobic hyperthermophilic bacterium known for its high amounts of hydrogen (H2) production. In the current study, the kinetic modeling was applied on the engineered strains of T. maritima that surpassed the natural H2 production limit. The study generated a kinetic model explaining H2 overproduction and predicted a continuous fermentation system. A Leudking-Piret equation-based model predicted that H2 production by Tma200 (0.217 mol-H2 g–1-biomass) and Tma100 (0.147 mol-H2 g–1-biomass) were higher than wild type (0.096 mol-H2 g–1 -biomass) with reduced rates of maltose utilization. …
