Hydrogen Fuel Cell Bench Test Rig  Background: Hydrogen Fuel Cells! Hydrogen Fuel Cell Controller Demonstration Hydrogen Fuel Cell Polarisation Curve You may have seen some previous posts (above) about my developmental test rig for hydrogen fuel cells.  Well I am pleased to say it has now finished the final stage of prototyping!   I have released the code on github and have tried to make it as user friendly as possible, however I would really appreciate some feedback! Even if ...
Hi all,   The latest update on my project for the chemical engineering nerds out there, how to get a polarisation curve from my fuel cell using a raspberryPi controller.   Unlike batteries, fuel cells do not lose voltage with time because you can keep feeding it fuel. Much like a car engine keeps working until the fuel is completely gone, whereas a battery has a gradual reduction in it's output with respect to it's state of charge (SOC). However, the voltage does vary with load, and th ...
Hi all,   The latest update on my project; using the raspberryPi as a controller for a hydrogen fuel cell with the intent on powering a remote controlled plane.   Hope you find the video interesting and inspiring, if so please click LIKE!   Regards,   Simon   ...

Hydrogen Fuel Cells!

Posted by howroyd Dec 2, 2013
Hydrogen fuel cells (in particular PEMFCs) are an exciting technology which has been around for a while now. Unfortunately, they haven't really take off (excuse the pun) due to their high cost, poor lifetime and slow transient performance.   1. So why are people still interested?   Well, firstly you have the good old "clean & green" argument. In operation, the take in oxygen (from the air) and hydrogen (the fuel), and give out heat, water and electricity. No carbon dioxide, monox ...
