Fuel Cell with unpressurised Hydrogen and Oxygen

AI Thread Summary
A fuel cell can be created using unpressurized hydrogen and oxygen from air, but the energy storage density of hydrogen at atmospheric pressure is low. Pressurizing hydrogen could enhance efficiency, making the setup more practical for energy production. Conducting this experiment in a DIY lab is feasible, but safety precautions are crucial due to the flammability of hydrogen. Relevant equations for predicting power output can be found in fuel cell literature, which is readily available online. Proper research and resources will aid in successfully executing this project.

Let's say I have a balloon full of Hydrogen that is STP, and outside this balloon I have normal air (containing oxygen) which is also STP. Is there a way to produce energy by turning these 2 items into a fuel cell, if so how practical is it (in a DIY setting) and is there anything that would make it more efficient (such as pressurising the hydrogen)?
 
Physics news on Phys.org
It is possible and pressure should not be a problem. Just keep in mind that the energy storage density is quite low with hydrogen at air pressure.
 
How could I perform this experiment in a DIY lab? Are there any equations that I can use to predict how much power I should be getting?
 
I searched amazon.com for "Fuel Cell" and got plenty of hits for books dedicated to fuel cells. One of these should suite you.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
