## [Hydrogen Fueling with Near-Field Communication](/spotlight/student-project/hydrogen-fueling-with-near-field-communication) /sites/default/files/spotlight-images/2025-04/md8_10887.JPG Christophorus Hansen, Frank Jin, Josh Lim, Alex Martin and Cheyenne Tu Department of Electrical and Computer Engineering - Electrical Engineering - Bachelor of Applied Science Vancouver ## **Our project** Our client, [IRDI System](https://irdisystem.com/), designs and develops components for the hydrogen fuel cell market, including the equipment used to fuel hydrogen-powered vehicles. Currently during refueling, only the vehicle is able to send fueling data to the station, but the station is unable to send any information (such as temperature and pressure) back to the vehicle. We were asked to develop a prototype solution for wireless bidirectional communication through a hydrogen fueling nozzle. > This technology could offer advantages over current unidirectional communication protocols by improving fueling times and efficiency – ultimately helping to reduce a barrier to the growth of the hydrogen-powered vehicle market. ## **Our design solution and process** Our team developed a nozzle transceiver prototype that implements bidirectional communication and fits within the small form factor of a standard hydrogen fueling nozzle. > We began by researching existing bidirectional communication standards and relatively quickly settled on near-field communication (NFC), which is currently used in a range of applications (Apple Pay, Compass cards, etc.) for its security and versatility. One of the most significant challenges of our project was trying to fit all the NFC circuitry and other elements into that nozzle.These sizing constraints heavily influenced our hardware selection and guided our design of a custom antenna. Once we had developed a prototype, we conducted a series of tests to ensure it was working as expected under a range of conditions required to meet hydrogen fueling standards, including distance, proximity and rotational position. > In terms of process, we each took on a specific role and then met weekly with our client to provide progress updates and make sure that we were on track with the prototype development.

We started with the hydrogen fueling valve reference and some general NFC design references. This meant we had to acquire a lot of knowledge in a short time. We took the initiative to build up our technical knowledge and apply it to a practical real-world solution. > The hardware design – and subsequent assembly – was a significant challenge. It seemed almost impossible at times to fit all the components into the tight space of the housing. ## **What we’re most proud of** We each brought very different skills and prior knowledge to this project. Everyone took responsibility and accountability for their area of focus, yet we all knew we could rely on our teammates to provide feedback and help us when needed. During the integration stage, we worked together by sharing ideas, troubleshooting challenges, and combining our efforts to drive the project forward. ## **Our project’s future** This project was a feasibility study to help advance the hydrogen vehicle industry. > Our working prototype represents an initial step in developing a potential bi-directional communication method for hydrogen fueling. The outcome of this project can be leveraged by our client to further advance the hydrogen vehicle industry.
