Fuel cell technology is coming on leaps and bounds but price verses output is always going to be a issue.

Fuel cell technology is coming on leaps and bounds but price verses output is always going to be a issue. 

The EFOY fuel cell generator is a German manufactured fuel cell generator that is ideal for caravans, camping and outward bound pursuits. So how much power do we need? You can work out your average power consumption roughly by working out how long your battery lasts from full charge.  E.g If you have a 100Ah battery and it lasts 4 days normally then you are using 25Ah per day.  25Ah = 300Wh at 12V which means it would take 18.5 days to go through 5L of fuel. So take the Ah you use per day, multiply by 12 to get Watt hours.  You will use 0.9L per 1000Wh. So you can work out how many litres per day.

 The Pros of fuel cell technology Vs fossil fuel Generators are:

Does not give off noxious gases (doesn’t burn the fuel it is a chemical reaction)

Gives off little heat

Can be used indoors

Is almost silent (noise is like a PC fan, but only when delivering the charge)

Only delivers power when your battery needs it, so it is very fuel efficient (a generator will burn fuel when not delivering any power)

The Cons Vs Generators

Generators deliver direct power

Generators will give much more power

Generators are cheaper

Fuel is more difficult to get hold of but we can help with that!

3.       It does not have an engine.  There are “fuel cells” that burn methanol to turn a dynamo. These are quite clean and efficient engines but are not a fuel cell.  A fuel cell works by reacting the methanol with platinum inside the stack.  This chemical reaction gives off electric current, carbon monoxide (as much as a small child breathes out), heat and water. The only noise is a pump to draw the fuel onto the stack to begin the reaction, and a cooling fan which only runs when the unit is delivering power.  The heat is very minor, not like an engine, but more like a computer.
