| The work presented in this thesis aims to address the obstacles that side reactions create in aluminum / H2O2 galvanic cells by proposing to control the cathodic reactant, H2O2, via encapsulation. Encapsulation of the cathodic reactant is achieved utilizing a non-ionic surfactant vesicle (i.e. niosome). Once encapsulated, a second control element over the cathodic reactant is provided. The use of a polymer will be implemented to achieve stability and render further control over the encapsulated H2O2 solution. Implementation of the proposed novel cathodic control system in aluminum / H2O2 galvanic cells aims to minimize aluminum consumption and increase cell efficiency. Cell performance is evaluated by several electrical characteristics which include and are not limited to cell overall power output, cell operational time, and energy production per consumption of the aluminum anode. Results indicate an average energetic output value of 0.57 KJ +/- 0.09 KJ versus 0.542 KJ +/- 0.05 KJ without the implementation of the proposed cathodic control system. In addition, a decrease of 15% in average aluminum consumption value was achieved with the use of the proposed system. |
