    摘要： The present invention relates to a method for manufacturing composite polymer electrolyte membranes coated with inorganic thin films for fuel cells using a plasma enhanced chemical vapor deposition (PECVD) method or a reactive sputtering method, so as to reduce the crossover of methanol through polymer electrolyte membranes for fuel cells and enhance the performance of the fuel cells. The manufacturing method of composite polymer electrolyte membranes coated with inorganic thin films for fuel cells according to the present invention is characterized to obtain composite membranes by coating the surface of commercial composite polymer electrolyte membranes for fuel cells with inorganic thin films using a PECVD method or a reactive sputtering method. The inorganic materials to form the inorganic thin films are chosen one or more from the group comprising silicon oxide (SiO2), titanium oxide (TiO2), zirconium oxide (ZrO2), zirconium phosphate (Zr(HPO4)2), zeolite, silicalite, and aluminum oxide (Al2O3). The present invention, by coating the polymer electrolyte membranes for fuel cells with inorganic thin films via a PECVD method or a reactive sputtering method, reduces the methanol crossover sizably without seriously reducing the ionic conductivity of polymer electrolyte membranes, thereby, when applied to fuel cells, realizes a high performance of fuel cells.

    摘要： A method for operating a polymer electrolyte membrane fuel cell at temperatures below the freezing point of water and an apparatus thereof are provided to prevent damage and performance degradation of the membrane-electrode assemblies. Non-humidified gas flows for several seconds before temperature of the polymer electrolyte membrane fuel cell falls below the freezing temperature of water when operation of the polymer electrolyte membrane fuel cell stops. Simultaneously, anode of the polymer electrolyte membrane fuel cell is filled with a solution having a low freezing point to prevent the temperature of a polymer electrolyte membrane fuel cell falling below the freezing point of water due to the lower ambient temperature in the winter. When the polymer electrolyte membrane fuel cell is restarted, the cell performance is not degraded reflecting that the present invention stably preserves the fuel cell.
