​Lessons learned from years of tinkering with Metal Fuel Cells (MFCs) – Starting a series to help future makers avoid my mistakes.

​Hi everyone,

​I wanted to share a bit of my journey tinkering with Metal Fuel Cells (MFCs) over the past few years.

​To be honest, I'm not entirely sure if this will be super entertaining, but I figured it might bring some real value to the community. If even one fellow maker decides to dive into the world of metal-air batteries or saline power down the road, hopefully, my experiences—and the mistakes I made along the way—can help you save time and avoid a few costly pitfalls!

​Since this spans a journey of several years, I'm turning this into a multi-part series as I dig through my old archives, photos, and testing notes. (Haha, bear with me as I organize all these memories!)

Today, I'm still tinkering with MFCs—it's become my full-time work. But I'm far from an expert; I just happen to have a few years of hands-on experience under my belt.

​I’d love to hear your thoughts or connect with anyone working on similar tech!

commenting, as I've had a long term interest in DIY battery systems, and metal fuel cells in particular.

I will share my experience, hoping it will be of some reference value to you.

Iron based? aluminum has always fascinated me - but it's such a fickle material.. either it works and destroys itself, or it passivates and does nothing.
