Abstract
Recombinant methanol fuel cell is a system integration including two elements that methanol reformer and Phosphoric acid fuel cell. The purpose of methanol reformer is doing reforming reaction that convert methanol into hydrogen for Phosphoric acid fuel cell[1]. The purpose of Phosphoric acid fuel cell is transforming chemical energy into electrical energy .The reforming of this research is OSRM(oxidative steam reforming of methanol),the reaction is combine POM with SRM. First of the research, we have to make sure the fuel of OSRM won’t corrode the channel of silicon. We use the gas-liquid map to analyze four different kind structure for which one is best for OSRM. In our research, we want use evaporator to vapor the fuel into gas phase to feed the fuel continuously. So we have to make sure the bubble of fuel is very small and uniformly distribute. In our research, we compare the four different structure to find out which structure is the best for our experiment. The four structure is empty, line, herringbone, herringbone with line. After we test the four different structure, we get the best structure for us is herringbone with line channel because the gases ratio is 65% and the bubble size distribution is 6-8 〖mm〗^2 which is the best result in our four different structure.
