Abstract: An embodiment ionomer for a fuel cell includes a copolymer having no carbon-oxygen bond, wherein the copolymer includes hydrophilic moieties disposed at both ends, wherein each hydrophilic moiety includes a styrene unit and a proton conductive functional group, and a hydrophobic moiety interposed between the hydrophilic moieties, wherein the hydrophobic moiety includes an ethylene-based unit, a butylene-based unit, an isoprene-based unit, or any combination thereof.

Abstract: An electronic device is provided. The electronic device includes a display; a memory for storing at least one audio signal; a communication circuit configured to establish wireless communication with an external device; and a processor electrically connected with the display, the memory, and the communication circuit, wherein the memory stores instructions for, when executed, causing the processor to: produce the at least one audio signal, receive data associated with a gesture through the communication circuit from the external device apply a sound effect, selected based at least in part on the data associated with the gesture, to the produced at least one audio source, and output or store a resulting audio signal, wherein the resulting audio signal represents application of the sound effect to the produced at least one audio signal.
