For ease of storage and handling, liquid fuels must be used. After hydrocarbons, not considered at present because of their low reactivity, methanol offers advantageous economic characteristics for this kind of utilization.The following report contains a brief description of these cells, their composition, and the fuels which can be used as well as a study of performances and costs over various periods of time. We have attempted to confirm the abovementioned expectation about electric traction and to set forth various application possibilities by estimating corresponding outlet potentials and by determining the means of research needed to achieve them.</div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"5 4","pages":"Pages 279-313"},"PeriodicalIF":0.0,"publicationDate":"1965-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(65)90019-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83032569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Seebeck coefficient, electrical resistivity and thermal conductivity are assumed to vary linearly with position. The performance criteria of interest include maximum no-load temperature difference, maximum coefficient of performance, maximum heat pumping capacity, coefficient of performance under conditions giving maximum heat pumping capacity and heat pumping capacity under conditions giving maximum coefficient of performance. Throughout the investigation it is assumed that the longitudinal surface of the thermoelement is insulated and that the fin conductances at the hot and cold junctions are infinite. The effect of spatial dependence of each property on the performance criterion is analyzed individually and then in physically appropriate combinations. It is shown that certain small linear variations in the Seebeck coefficient and the electrical resistivity act to increase all the performance criteria. However, small linear variations in the thermal conductivity decrease the performance criteria. In addition, it is shown that the spatial dependence of the thermal conductivity is not nearly as important as the dependence of the electrical resistivity and the Seebeck coefficient. Therefore, a net increase in the performance criteria should be possible through the use of controlled spatial property dependence.</div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"5 4","pages":"Pages 383-405"},"PeriodicalIF":0.0,"publicationDate":"1965-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(65)90025-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84262791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No material balance equations and no trial and error procedures are needed, while the mathematical “problems” are confined to the solution of a quadratic equation as the most involved step.Apart from carbon deposition boundaries, CH4 and H2O “isobars” and curves of constant reversible oxidation potential in fuel cells with O= transport and CO3= transport have been computed for temperatures of usual interest. The method has been outlined for each of these cases.Some theoretical consequences of the trend for p(H2O) to remain constant in low or intermediate temperature fuel cells with aqueous electrolyte, have been pointed out in connection with the possibility of C deposition on highly active fuel electrodes.An example pertinent to the use of the diagrams shown, is given in Appendix 2, where also the calculation of the complete equilibrium composition from CH4 isobars is discussed.</div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"5 4","pages":"Pages 365-382"},"PeriodicalIF":0.0,"publicationDate":"1965-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(65)90024-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77018578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
