“…35 Many recent efforts focus on Nafion ® as the electrolyte with Pt and Pd as sensing electrodes. [61][62][63][64] A Pd on carbon fiber (Pd/CF) with varying Pd loading (5, 10, and 20 wt%) was utilized recently with Nafion ® membranes where the 10% Pd/CF showed a linear sensor response to H 2 concentration in the range of 200-10000 ppmv with a sensitivity of 0.0131 μA/ppmv H 2 . 61 Due to their resemblance to PEMFCs, this particular design has been tested for hydrogen sensing in conditions relevant for PEMFC operation.…”

Efforts to create a sustainable hydrogen economy are gaining momentum as governments all over the world are investing in hydrogen production, storage, distribution, and delivery technologies to develop a hydrogen infrastructure. This involves transporting hydrogen in gaseous or liquid form or using carrier gases such as methane, ammonia, or mixtures of methane and hydrogen. Hydrogen is a colorless, odorless gas and can easily leak into the atmosphere leading to economic loss and safety concerns. Therefore, deployment of robust low-cost sensors for various scenarios involving hydrogen is of paramount importance. Here, we review some recent developments in hydrogen sensors for applications such as leak detection, safety, and process monitoring in production, transport, and use scenarios. The status of methane and ammonia sensors is covered due to their important role in hydrogen production and transportation using existing natural gas and ammonia infrastructure. This review further provides an overview of existing commercial hydrogen sensors and also addresses the potential for hydrogen as an interferent gas for currently used sensors. This review can help developers and users make informed decisions about how to drive hydrogen sensor technology forward and to incorporate hydrogen sensors into the various hydrogen deployment projects in the coming decade.

“…17 Proton exchange membrane fuel cell (PEMFC) type gas sensors have been considered as one of the most promising gas detection equipment due to their low power consumption (in fact it has no need for external voltage and works at room temperature), low cost associated along with features such as portability, good linear signal and fast response. 18,19 In order to ensure practical benets of the PEMFC in the eld of gas sensing, the following problems of Pt/C electrode materials must be solved: (i) poor selectivity to target gas, (ii) low a State Key Laboratory on Integrated Optoelectronics, College of Electronic Science and Engineering, Jilin University, Changchun, 130012, China.
