How much electricity does a kg of hydrogen produce?

In electrical terms, the energy density of hydrogen is equal to 33.6 kWh of usable energy per kg, versus diesel which only holds about 12–14 kWh per kg. What this really means is that 1 kg of hydrogen, used in a fuel cell to power an electric motor, contains approximately the same energy as a gallon of diesel.

How much does it cost to produce hydrogen from electricity?

At current electrolyzer efficiencies, in order to produce hydrogen at lower than $3.00/kg, electricity costs must be lower than 4 and 5.5 cents per kWh. For an ideal system operating at 100\% efficiency, electricity costs must be less then 7.5 cents per kWh to produce hydrogen at lower than $3.00/kg.

How much ampere does a hydrogen fuel cell produce per hour?

Assuming that the cell can react 1 mol (22.4 liters) of hydrogen per hour, and it is 100\% efficient, the answer would be 53.6Amp produced per hour from 1 mole or 22.4 liters of hydrogen gas. By dividing 22.4/53.6, we get 1 ampere/hour from 0.4179 liter of H2, for this theoretically 100\% efficient fuel cell capable of reacting 1 mol H2 per hour.

How many coulomb per second do you need to produce hydrogen?

To produce it of (for example) seawater you need 2*96300=192600 Coulomb of electricity. The number 96300 Coulomb menas 1 mole of electrons. Because hydrogen exists under real conditions as H2 we need 2 mole of electrons to produce 2 g of the gas. 1 Coulomb per second is 1 Amp.

What is the maximum power output of a hydrogen generator?

So, the generator in our example will have a maximum output of 1.6 LPM (64 ml x 25.4 amps) Generation of Hydrogen is based on electrolysis, which is governed by the laws of physics. This process was studied almost 200 years ago by Michael Faraday, who subsequently published “Faraday’s Laws of Electrolysis”.
