How much hydrogen gas is needed for the fuelcell?

12 June 2023 1 4K Report

I have signlecell fuelcell. area of this fuelcell is 144cm2.

I want to oprate this fuelcell which can giveme 100 A output. so could anyone giveme Suggestion that howmuch liter of hydrogen i needed to run is this fuelcell for 24hours.

this fuelcell works at very low pressure which is in between 0.006 bar to 0.012bar only.

I have one hydrogen cylinder which is filled with 200 bar pressure and has 50 Liter gas in the cylinder. please help me out. Thank you.

Dear friend Daxay Vaghani

Specific information you will need to find yourself on "how much hydrogen gas is needed for a fuel cell with an area of 144cm2, operating at 100A for 24 hours". The amount of hydrogen required depends on the efficiency of the fuel cell, which is higher when the fuel cell is new compared to the end of its life. Original equipment manufacturers (OEM's) use the term beginning of life (BOL) and end of life (EOL). The efficiency of a fuel cell BOL is approximately 51%, EOL is approximately 45% (https://www.energy.gov/eere/fuelcells/hydrogen-fuel-basics).

The amount of hydrogen gas needed for a fuel cell depends on the efficiency of the fuel cell and the amount of energy you want to generate. For example, to run a **200 kW fuel cell** for **8 hours**, you would need approximately **94 kg** of hydrogen gas.

My friend filed a patent on hydrogen fuel cell, maybe we can bring onboard, if there is deeper insight in this question.

There are some resources which I am sharing with you.

Is there a specific fuel cell you have in mind?

Dear all, I was wondering if anyone knows whether MGLtools and Autodock can run on Mac OS?

I have tried to download the 64-bit version of MGLtools however, as many times as I have downloaded and uninstall the programs, an error arises that the app needs to be updated. Thank you.
