Huff, J R

Successful operation of a direct methanol/air fuel cell system depends upon appropriate integration of the fuel cell components and accommodation of the need for heat and mass transfer within the system. The features of the system that must be considered separately and in an interactive fashion are: (1) the physical state of the fuel feed stream, (2) electrode characteristics, (3) characteristics of the electrolyte, (4) product water removal, (5) heat transfer into our out of the stack, and (6) methanol loss modes. The operating temperature and pressure will be determined, to a large extent, by these features. An understanding of the component features and their interactions is necessary for initial system considerations for direct methanol/air fuel cells.
