How do you use algae to produce hydrogen gas for use in fuel cells?

Anyone can do it, but the problem is doing it efficiently enough so that it competes with the price of Oil.
1. Grow some algae in a vat using photosynthesis to turn CO2 and sunlight into sugar.
2. Dump out the algae into a filter, collect the sugars.
3. Feed the sugar to a rat in a cage. The rat turns a crank, producing electricity.
4. Have the electricity run through water, separating the oxygen from the hydrogen.
5. Collect up the Hydrogen and put it in the fuel cell.
The only problem is that the amount of energy we need to roll back INTO the process of making the energy is so large that this process won't compete with oil.
How to do it efficiently? Well get your top geneticists on the ball at editing the DNA code to get the algae to produce hydrogen instead of sugar. It can be done. It's just very hard.

What are the two gases used to produce electricity in fuel cells?
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
What gas combines with oxygen in fuel cells?
hydrogen
What are the waste byproducts of hydrogen fuel cells?

How do hydrogen fuel cells work?
The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions.The electrons flow out of the cell to be used as electrical energy. The hydrogen ions move through the electrolyte membrane to the cathode electrode where they combine with oxygen and the electrons to produce water. Unlike batteries, fuel cells never run out. In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.
Why is hydrogen gas a good option for an alternative fuel to fossil fuel?
fossil fuel may be depleted soon. but hydrogen gas can me made available. also, if there are cheaper ways to split water into hydrogen and oxygen, then the better it is as water is available everywhere ----------------------------------------------------------------- Fuel cells produce hydrogen gas from fossil fuels, and renewable fuel sources. Hydrogen can also be made from other energy (electric) sources and electrolysis of water, but compressing and transporting it poses it's own problems. Despite this, the production of hydrogen as a fuel source uses more energy than can be gained from the hydrogen itself.
Fuel cells produce energy from hydrogen by?
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
Fuel cells produce chemical energy by combining?
Carbon and hydrogen
Fuel cells use oxygen and what kind of gas and produce energy and water?
hydrogen
What is only byproduct of fuel cells?
The only byproduct of an oxygen and hydrogen fuel cell is water. There are other less common types of fuel cells, such as zinc and air cells, which do produce other byproducts.

Is hydrogen fuel cells fossil fuels?
no because hydrogen fuel cells are renewable
How much does a hydrogen car cost?
The Honda Clarity cost $300,000 each, but hydrogen fuel cells are expensive to produce and some are fragile.
Hydrogen fuel cells combine hydrogen and oxygen to produce water and energy Assume 1 kg of fuel is used and the mass of the water produced is 1.10 x 10-11 kg How much energy is produced by this fuel?

Do Hydrogen fuel cell have impact on society?
Yes, of course. It takes raw materials and engergy to produce a hydrogen fuel cell. It then takes raw materials and energy to produce the hydrogen fuel. However, the result of the hydrogen fuel cell combustion is water - this is a significant improvement over regular internal combustion engines which produce all kinds of exhaust fumes.Assuming hydrogren fuel cells become wide spread then society will change in many ways from new jobs and new fuel refineries/distribution to new language/slang for the HFCs etc...
What is true is true regarding hydrogen fuel cells and hydrogen fuel cells and hydrogen fusion?
More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX
What is the difference between hydrogen fuel cells and hydrogen fussion?
In fuel cells the hydrogen is oxidised to water. In fusion 2 different isotopes of hydrogen (deuterium and tritium) fuse together to form helium.
Who invented hydrogen fuel cells?
