  Vehicles powered by hydrogen fuel cells combine the benefits of battery-powered electric vehicles and internal combustion engines (ICEs). You get the environmental and performance benefits of electricity, with the same refueling convenience as you get with ICE vehicles. But for most of us, hydrogen fuel cells are still mysterious and unattainable. In reality, you can buy one right now. To demonstrate how practical they are, Alfonso Delgado Ollero built a miniature hydrogen fuel cell to power an RC truck.

  Hydrogen combines with oxygen in the air to produce water. As it does, it also produces electricity and we can use that electricity to power devices and even vehicles. The only reasons hydrogen fuel cell vehicles aren’t common are that it takes a lot of energy to produce the hydrogen in the first place and the energy density is relatively low. Those practical concerns are relevant when talking about the future of the automotive industry, but they shouldn’t prevent makers from experimenting with hydrogen fuel cells. You can buy small hydrogen fuel cells, like the 12W unit used in this project, from online retailers for less than $700. You can also purchase cartridges of hydrogen or even make your own through electrolysis (read up on the safety precautions first).

  We had some fun with our partners - Digi-Key, Analog Devices, Harting, and Würth Elektronik - to not only develop 10BASE-T1L SPE prototyping tools, but to also put together a helpful demo/use case. The video below provides a quick look at the new prototyping tools and then moves to the demo.
