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 this relationship is captured in a polarisation curve.

 

Hope you find the video interesting and inspiring, if so please click LIKE!

 

Regards,
