Electro-catalytic recharging composition
View Patent ↗A composition useful for the fueling and refueling of electrochemical devices is described. The composition comprises an ion-conducting medium such as an electrolyte, and catalyst nanoparticles. Unlike traditional electrodes, such as those typically used in electrolyzers and fuel cells, the inventive composition may be quickly drained from the device and refilled to maintain maximum cell performance. In addition, the electro-catalytic charging composition can be stored as a solid for safe handling; for example in a portable cartridge.
1. A portable cartridge comprising an electro-catalytic fueling composition suitable for use in recharging an electrochemical system, the composition comprising an electrolyte and catalytic nanoparticles, wherein the composition is in solid phase suitable for storage within the portable cartridge, and wherein the portable cartridge is configured to permit the introduction of fluid therein to change the phase of the composition from solid to liquid.
