The general approach will be to utilize a radioisotope to produce chemical intermediates, which will be reacted in an electrochemical cell. In particular, the water cycle will be used, in which water is first decomposed via radiochemical reaction. The decomposition products are then reacted electrochemically, producing electricity and water.</p> <p>In particular, three primary studies were conducted. First, selective electrode screening and development was carried out. These results were then considered in generating possible cell designs. These designs were mathematically modeled and solved, either analytically or numerically (using a control volume method), to analyze cell performance factors such as reactant utilization, current distribution, and pressure buildup. Lastly, attempts were made to improve radiolysis yield.</p> <p>Model results indicate that without improvement of radiolysis efficiency, it is not practical to construct a 35mW device based on these designs. Research failed to provide a method for improving radiolysis efficiency, making a 35mW device infeasible within 1cm <sup>3</sup>. However, development of a 10mW device within 1cm <sup>3</sup>would be possible using the designs and materials described here.</p> 2008-01-14 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1200158754 http://rave.ohiolink.edu/etdc/view?acc_num=case1200158754 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
