摘要:
The polymer electrolyte membrane for a fuel cell includes a hydrophilically surface-treated polymer particle filler, and a proton conductive polymer. The polymer electrolyte membrane has improved properties in conductivity, swelling, tensile strength and modulus.
摘要:
A substrate for a flexible display device, an OLED display device including the same, and associated methods, the substrate including a composite of an inorganic layered compound and a moisture-absorption material, and a polymer resin.
摘要:
A method of driving a heating unit for a fuel cell reformer, a reformer applied with the method for driving the heating unit, and/or a fuel cell system including the reformer. The method includes: supplying an oxidant to the heating unit and absorbing the oxidant by a fuel oxidizing catalyst of the heating unit; supplying a fuel at an excessive amount to the heating unit and absorbing the fuel by the fuel oxidizing catalyst of the heating unit; and supplying the fuel and the oxidant to the heating unit at a stoichiometric ratio of the fuel to the oxidant ranging from 1:1 to 2:1, wherein the heating unit generates heat through an oxidizing catalyst reaction between the fuel and the oxidant.
摘要:
A fuel oxidizing catalyst, a method of preparing the same, and a reformer and a fuel cell system including the same. In one embodiment, the fuel oxidizing catalyst for a fuel cell includes CeO2, MO (wherein M is a transition metal), and CuO. In this embodiment, the fuel oxidizing catalyst has a relatively high (or excellent) catalytic activity for a fuel oxidizing catalyst reaction and performs a fuel oxidizing catalyst reaction at a relatively low temperature even though it does not include a noble metal.
