Water Fuel Cell Test Data


One litre of hydrogen weighs 0.09 grams :
One gram of water contains 1.23 litres of hydrogen.
Energy released from burning hydrogen is 142.35 kJ/gH


Instruments and Equipment used


Experimental low current wfc.filled with tap water.Stop watch.Scales type Satrue model

SB-200 200g 0.1 gram steps Avo Mk 9 Test Meter.Precision Gold model Wgo20 Digital Test Meter.

Racal Dana True RMS Voltmeter model 9300.Hameg Oscilloscope model 203-5.

Tektronix 547 oscilloscope.

The water fuel cell was pulsed at 6 Khz Square wave 50:50 duty cycle.


Duration of test in min. = 60

RMS Voltage V = 7.5

Ampmeter I, amperes = 0.06

Power P,watts hour (P=VxIxmin/60 0.45

Mass of wfc in grams = 106.9

Mass change in grams m = 0.4

Evaporating water mass me, = 0.04

Mass of water split into gasses, m-me = 0.36

Released hydrogen quantity 0.36x1.23x0.09= 0.03985

Energy content of produced hydrogen (W=0.03985x142/3.6)= 1.57186

Energy Efficency (Wx100/P) % )= 349 %

Energy Efficency of this WFC is 349 % or overunity

INPUT--H2+O2 cc/sec---H2 only cc/sec---H2 Lit/hr

0.5 A-----7.00--------------4.66-------------16.776
1.0 A-----8.66--------------5.78-------------20.808
1.5 A-----11.66-------------7.78-------------28.008
2.0 A-----14.00-------------9.33-------------33.588
3.0 A-----16.36------------10.91-------------39.276
4.0 A-----18.00------------12.00-------------43.200


DC Voltage = 12v Current I = 0.5 Amps produces 7.00 cc/sec of H2+O2

It takes 2.15 W/h to produce 1 Litre of H2+O2 = 100% Efficiency

Time to produce 1 Litre of H2+O2 at 7cc/sec is = 1000/7 = 142.85 sec

Energy input in W/h = 12 Volts x 0.5 Amps x 143/3600 = 0.238 W/h

Energy Efficiency Of This WFC = 2.15W/h/0.238W/h = 9.03 x 100 = 903% Efficient or Overunity
