Abstract: In a redox flow battery (RFB), the base solvent of the electrolytes tends to migrate across the barrier layer from one electrode toward the other. This can result in a volume and concentration imbalance between the electrolytes that is detrimental to battery efficiency and capacity. Compatible electrolytes can be mixed to rebalance the system, but for incompatible electrolytes mixing is not a viable option. To this end, the RFB herein includes a separator that recovers base solvent from the vapor phase of one of the electrolytes and returns the recovered base solvent to the other electrolyte to thereby reverse the imbalance.

Abstract: A method of testing a gas includes providing a sensor including a sensing electrode that includes a catalyst comprising palladium, and a counter electrode that includes a metal catalyst. An electrolyte is disposed between the sensing electrode and the counter electrode, and an external electrical circuit connects the sensing electrode and the counter electrode. The gas is contacted with the sensing electrode in the absence of a voltage bias applied to the sensing and counter electrodes. A capacitive response is detected that is produced by the exposure of the sensing electrode to the gas in the absence of a voltage bias applied to the sensing and counter electrodes.
