COMPOSITE POROUS MEMBRANE, METHOD FOR PRODUCING COMPOSITE POROUS MEMBRANE, SOLID POLYMER ELECTROLYTE MEMBRANE, AND FUEL CELL |
摘要 |
It is intended to provide a composite porous membrane comprising a fibrous filler-containing polymer film or sheet, characterized by having a large number of pores with an exposed fibrous filler formed by irradiation with an ultra-short pulse laser with a pulse width of 10 -9 seconds or less, and to provide a polymer electrolyte membrane having the pores that are filled with a polymer electrolyte. According to the present invention, an inorganic-organic or organic-organic composite porous membrane can be obtained, which can be prepared as a thin membrane and is highly durable with high strength and a reduced cross-leak of fuel gas. This composite porous membrane can be used as a solid polymer electrolyte membrane to obtain a fuel cell improved in output voltage and electric current density. |
