摘要:
The present invention describes an improved membrane for Redox Flow Batteries, in particular for Vanadium Redox Batteries and energy storage systems and applications employing the Vanadium Redox Cells and Batteries. Redox Flow Batteries involve the use of two redox couple electrolytes separated by an ion exchange membrane that is the most important cell component.
摘要:
A facilitated pressure fluctuation prevention tank structure capable of preventing a pressure fluctuation in a gas phase part resulting from a temperature variation without allowing stored liquid to come into contact with air, comprising respiration bags (3) installed in the gas phase part (2) of a tank (1) and expanding and contracting in communication with the atmosphere and manholes (21) having communication holes (22) for the respiration bags to communicate with the atmosphere and having the respiration bags attached thereto so as to be suspended in the gas phase part, the respiration bags (3) further comprising an air sealability, acid resistance, and expandability.
摘要:
This invention provides a redox fuel cell comprising an anode and a cathode separated by an ion selective polymer electrolyte membrane; means for supplying a fuel to the anode region of the cell; means for supplying an oxidant to the cathode region of the cell; means for providing an electrical circuit between the anode and the cathode; a non-volatile catholyte solution flowing in fluid communication with the cathode, the catholyte solution comprising a redox mediator which is at least partially reduced at the cathode in operation of the cell, and at least partially regenerated by, optionally indirect, reaction with the oxidant after such reduction at the cathode, and a transition metal complex of a multidentate N-donor ligand as a redox catalyst catalysing the regeneration of the mediator.
