摘要：Various aspects of the present invention relate to current collector arrangements and compositions in an electrochemical device. In an electrochemical device used to convert chemical energy via an electrochemical reaction into electrical energy, the electrical energy may be collected via a current collector of the present invention. The electrochemical device may be used anywhere that electrical energy is needed. Examples of electrochemical devices include a fuel cell and a battery; other examples include an oxygen purifier and an oxygen sensor. The current collector may include an electrically conducting core and an electrical connector. In certain embodiments, the electrically conducting core may be made out of a material able to withstand the operating conditions of the electrochemical apparatus, which may include, for example, a liquid anode or cathode, or a reducing or oxidizing environment; in other embodiments, the electrically conducting core may be surrounded and protected from the operating conditions by one or more materials. In some embodiments, additional materials may be used to facilitate electrical communication within the device. For example, an interconnect able to withstand the operating conditions may be used to connect two or more cells within the device.
