Abstract: A computer implemented method includes monitoring a gas analyte level associated with a battery system using a first gas sensor and monitoring at least one variable of the battery system. The method includes determining whether there exists a correlation between the monitored gas analyte level and the monitored at least one variable of the battery system. The method includes determining whether there is an electrolyte leak from the battery system based on the determination of the correlation.

Abstract: Provided are a composition including a hydrogen-selective porous composite, a hydrogen gas sensor device including the hydrogen-selective porous composite, a kit for detecting hydrogen including the hydrogen gas sensor device, and a method for detecting hydrogen including contacting a hydrogen-comprising gas to the hydrogen selective porous composite. The method may include, for example: providing a hydrogen-comprising gas; providing a hydrogen-selective porous composite, the hydrogen-selective porous composite comprising cerium oxide; contacting the hydrogen-comprising gas to the hydrogen-selective porous composite; and selectively detecting hydrogen in the hydrogen-comprising gas according to a decrease in an electrical resistance of the hydrogen-selective porous composite.

Abstract: A gas monitoring system and method are provided. In one embodiment, a gas monitoring system includes a gas monitoring unit in a reactor containment environment, a gas monitoring unit controller in a reactor non-containment environment, and a high temperature or industry compliant cable interconnecting the gas monitoring unit with the gas monitoring unit controller. Various sensors on the gas monitoring unit detect conditions of the reactor containment environment, including hydrogen gas concentration.

Abstract: A hydrogen sensitive composite sensing material based on cerium oxide with or without additives to enhance sensitivity to hydrogen, reduce cross-sensitivities to interfering gases, or lower the operating temperature of the sensor, and a device incorporating these hydrogen sensitive composite materials including a support, electrodes applied to the support, and a coating of hydrogen sensitive composite material applied over the electroded surface. The sensor may have in integral heater. The sensor may have a tubular geometry with the heater being inserted within the tube. A gas sensor device may include a support, electrodes applied to the support, and a dual sensor element to cancel unwanted effects on baseline resistance such as those resulting from atmospheric temperature changes. The hydrogen sensitive composite material or other gas sensitive materials may be used in the dual element gas sensor device.
