With a background and know-how in gas sensor development, AppliedSensor set out to develop a highly selective hydrogen gas sensor to be used as a safety device for the coming hydrogen economy. Part of the strategy was to partner with an automotive manufacturer to develop an on-board safety sensor and the result was the HSS-440 module, which incorporates high-performance sensing based on advancements in Field Effect (FE) technology designed specifically for fuel cell and hydrogen-powered vehicles. The modules are mounted in the car cabin, under the hood and in the trunk area to detect hydrogen gas leaks at levels far below the established lower explosion limit of four percent in-air.

The steps that we took in working closely with an OEM and the challenges that we faced and overcame to meet the stringent automotive standards have assisted our partner, BMW, in bringing their hydrogen powered vehicle, the Hydrogen 7, to market. The presentation will address these challenges and how we overcame them.
