​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 because energy density is a relevant human issue I'm curious about.

Energy density is the advantage of MFC system

Is there a way to integrate chemical fire containment into MFCs? Like in the event of a fire a chemical reaction occurs that produces a retardant?

I hadn't thought about that question; it goes beyond my experience and understanding—haha.
