Materials, the film uses COC (cycloolefin copolymer) resin, the valve EPDM (EPDM) rubber. The original use of all components are polypropylene resin. Compared with polypropylene resin, COC resin and EPDM rubber have higher shape stability after molding, which improves product yield. In order to realize the practical use of the fuel cell, it is necessary to increase the mass productivity of the micro-pump for fuel supply, so that the research on the material has been intensified.
"Increased mass production" Stamford exhibited a new miniature fuel cell pump
Nikkei BP news agency reported on November 11, 2005: On November 9, 2005 to 11 at the Japan Science and Technology Museum at the "16th Micromechanics Exhibition", Japan's Star Micronics show The concept of a notebook PC is intended for use in a fuel pump for fuel cells and the like. The micropump is a Diaphragm Type using piezoelectric elements and includes two models, "SDMP305" with a maximum flow rate of 5 ml / min and "SDMP301" with a maximum flow rate of 1.5 ml / min. The original product is the maximum flow of 1.5ml / min "SDMP205." In order to improve mass productivity, this time in addition to changing the diaphragm and valve materials used, but also by improving the internal structure, increased without changing the size to increase the maximum flow model.
