Show moreThis study investigates the spiritual subjectivities of pastors in the Mainstream White Middle Class Evangelical Church in the context of American capitalism. The Evangelical church carries extreme amounts of power and influence in shaping the beliefs of individuals in American society. However, very little pointed research of pastors' spiritual subjectivities that guide their teachings and views in this sub-sect of church culture is present in academia. Anthropology, along with other disciplines, often focuses on dominant churches from an etic perspective of politics and power relations without fully considering the spiritual beliefs of pastors. This etic perspective can miss the deeply interwoven factors, including understanding of the Scriptures and pastors' roles in their congregations, challenges associated with religious consumerist competition, and conceptualizations of church "success" that shape pastors subjectivities, and in turn help shape American Christian culture. Pastors navigate the tension between the broader capitalistic social forces and their spiritual and Biblical beliefs as many pastors of the church aim to change the unquestioned adherence to these ideals. Building on my seven years of experience as a pastor in the Orlando area and drawing on current research with a group of Evangelical pastors, I demonstrate in this study that although capitalistic social forces shape many ideals of individuals in the American Evangelical church culture, understanding pastors' spiritual subjectivities is crucial when investigating the influence of the church in America.

Abstract / Description
Polymer electrolyte membrane fuel cells (PEMFCs) have recently acquired much attention as alternatives to combustion engines for power conversion. The primary interest in fuel cell technology is the possibility of 60% power conversion efficiency as compared to the 30% maximum theoretical efficiency limited to combustion engines and turbines.

Show morePolymer electrolyte membrane fuel cells (PEMFCs) have recently acquired much attention as alternatives to combustion engines for power conversion. The primary interest in fuel cell technology is the possibility of 60% power conversion efficiency as compared to the 30% maximum theoretical efficiency limited to combustion engines and turbines. Although originally conceived to work with hydrogen as a fuel, difficulties relating to hydrogen storage have prompted much effort in using other fuels. Small organic molecules such as alcohols and formic acid have shown promise as alternatives to hydrogen in PEMFCs due to their higher stability at ambient conditions. The drawbacks for using these fuels in PEMFCs are related to their incomplete oxidation mechanisms, which lead to the production of carbon monoxide (CO). When carbon monoxide is released in fuel cells it binds strongly to the platinum anode thus limiting the adsorption and subsequent oxidation of more fuel. In order to promote the complete oxidation of fuels and limit poisoning due to CO, various metal and metal oxide catalysts have been used.Motivated by promising results seen in fuel cell catalysis, this research project is focused on the design and fabrication of novel platinum-composite catalysts for the electrooxidation of methanol, ethanol and formic acid. Various Pt-composites were fabricated including Pt-Au, Pt-Ru, Pt-Pd and Pt-CeO2 catalysts. Electrochemical techniques were used to determine the catalytic ability of each novel composite toward the electrooxidation of methanol, ethanol and formic acid. This study indicates that the novel composites all have higher catalytic ability than bare Pt electrodes. The increase in catalytic ability is mostly attributed to the increase in CO poison tolerance and promotion of the complete oxidation mechanism of methanol, ethanol and formic acid. Formulations including bi- and tri-composite catalysts were fabricated and in many cases show the highest catalytic oxidation, suggesting tertiary catalytic effects. The combination of bi-metallic composites with ceria also showed highly increased catalytic oxidation ability. The following dissertation expounds on the relationship between composite material and the electrooxidation of methanol, ethanol and formic acid. The full electrochemical and material characterization of each composite electrode is provided.
