Hydrogen fuel cell co-generation home heating system, small unit proof of concept using off the shelf parts. A fuel cell is about 45% efficient at generating electricity, so for 1 kilowatt of electrical power produced approximately 1 kilowatt of heat is produce by the fuel cell stack. As a by-product, water is produced as well. This video demonstrates heating of my 20 foot boat while charging its battery bank and then heating of a 200 square foot room in my home using a small 500 watt oil filled electric heater to control the system.
