Purposeful miniature hydrogen gas cell powers RC truck
September seventeenth, 2022—
Autos powered by hydrogen gas cells mix the advantages of battery-powered electrical autos and inner combustion engines (ICEs). You get the environmental and efficiency advantages of electrical energy, with the identical refueling comfort as you get with ICE autos. However for many of us, hydrogen gas cells are nonetheless mysterious and unattainable. In actuality, you should purchase one proper now. To show how sensible they’re, Alfonso Delgado Ollero constructed a miniature hydrogen gas cell to energy an RC truck.
Hydrogen combines with oxygen within the air to provide water. Because it does, it additionally produces electrical energy and we are able to use that electrical energy to energy units and even autos. The one causes hydrogen gas cell autos aren’t frequent are that it takes a variety of vitality to provide the hydrogen within the first place and the vitality density is comparatively low. These sensible issues are related when speaking about the way forward for the automotive business, however they shouldn’t stop makers from experimenting with hydrogen gas cells. You should buy small hydrogen gas cells, just like the 12W unit used on this mission, from on-line retailers for lower than $700. You can too buy cartridges of hydrogen and even make your individual by electrolysis (learn up on the security precautions first).
Whereas this mission makes use of an off-the-shelf hydrogen gas cell, it nonetheless wanted one thing to manage the operation and energy output. An Arduino Nano board screens the working voltage and shuts the system down whether it is working too lengthy or in an open circuit. It additionally prompts a pump when essential to purge the water that accumulates because the hydrogen bonds with oxygen. To stabilize the voltage output from the hydrogen gas cell, a DC-to-DC buck converter feeds electrical energy at a relentless voltage to lithium-ion battery cells. These act like capacitors to account for peaks in energy demand that exceed the output of the hydrogen gas cell.
Ollero mounted all of these parts within a field that attaches onto the mattress of an RC truck. The facility output wires connect to the RC truck’s commonplace battery enter. This labored effectively and the RC truck drove round with none points. However the RC truck is only a demonstration and this hydrogen gas cell setup may very well be helpful for a lot of different functions.
