Due to a combination of environmental and economic motivations, there is a strong impetus to transition away from fossil fuels towards renewable sources of energy. Critical to achieving this goal will be technologies that allow for the storage and transmission of energy derived from renewable sources. Hydrogen fuel cells may play a significant role in making this a reality, allowing for the use of hydrogen as a non-carbon based fuel, in particular for vehicle applications. Hydrogen fuel cells directly convert chemical energy into electrical energy, with only water vapor and heat as waste products.

520 $a Due to a combination of environmental and economic motivations, there is a strong impetus to transition away from fossil fuels towards renewable sources of energy. Critical to achieving this goal will be technologies that allow for the storage and transmission of energy derived from renewable sources. Hydrogen fuel cells may play a significant role in making this a reality, allowing for the use of hydrogen as a non-carbon based fuel, in particular for vehicle applications. Hydrogen fuel cells directly convert chemical energy into electrical energy, with only water vapor and heat as waste products.
520 $a There are challenges facing fuel cell technology that inhibit its wider implementation. One of the most significant of these is the cost of the platinum that is typically used in fuel cells to catalyze the oxygen reduction reaction (ORR), which is the bottleneck reaction in hydrogen fuel cells. The rarity and expense of platinum significantly add to the cost of fuel cells, thus reducing their economic viability. Therefore there is much interest in developing catalysts from alternative materials with a lower cost. A second, and related issue facing fuel cells is the degradation over time of the support structure that puts the catalyst into electrical connection with the external load. The carbon structure that currently serves as the standard catalyst support degrades over time under the harsh operating conditions of the cell, leading to catalyst agglomeration and reducing the lifetime of the cell. It is therefore desirable to develop support structures that will be more stable, while still providing electrical conductivity.
520 $a The following presents original research pertaining to the development of catalyst/support materials making use of non-noble metal oxides synthesized by means of wet chemical methods. Metal oxides such as manganese oxide and titanium oxide are capable of serving as support materials and (in the case of alkaline fuel cells) even as catalysts. Wet chemical techniques were chosen due to their relative economy and simplicity, obviating the need for expensive specialized equipment, and the ease with which such processes may be scaled up. The aim of this research was the development of a more stable catalyst/support structure, replacing the graphitic carbon that is traditionally used, focusing on both alkaline and acidic systems.
