Abstract

The invention belongs to the technical field of hydrogen concentration detection and monitoring, and discloses a hydrogen sensor and application thereof. According to the sensor, room-temperature ionic liquid N,N,N-trimethyl-N-sulfobutyl ammonium hydrogen sulfate is used as an electrolyte, and platinum black is used as a catalyst. The response current of the sensor and the concentration of H2 are in a linear relation, and the sensor not only has high sensitivity, good selectivity and fast response recovery, but also has stable performance in a high-humidity environment. The sensor provided by the invention overcomes the problem that an electrochemical gas sensor cannot be applied to high humidity, and has a good potential application prospect on high-temperature and high-humidity ships. Moreover, the sensor does not need an inner support and a liquid storage tank, the structure is more simplified, the size is smaller, an anti-vibration layer is additionally arranged, and the sensor has better firm anti-vibration performance.

Description

technical field

[0001] The invention belongs to the technical field of hydrogen concentration detection and monitoring, and in particular relates to a hydrogen sensor and its application. Background technique

[0002] International shipping transport accounts for more than 80% of global trade. Economical but polluting diesel engines and cheap heavy-duty fuels have become the default choice for offshore power generation due to cost-of-ownership advantages. Despite technological advances, shipping remains a global contributor to greenhouse gases (GHGs), volatile organic compounds (VOCs), particulate matter (PM), hazardous air pollutants (NO X and SO X ) significant contributor to emissions. Shipping activities are estimated to contribute to global carbon dioxide (CO2 2 ) of 3-5% of emissions, accounting for global SO X more than 5% of emissions. In April 2018, the International Maritime Organization (IMO) adopted mandatory technical and operational energy efficiency meas...
