Building an electrolysis cell for a HHO torch

Help determining amps in an electrolysis cell

I'm a young student and I'm building an electrolysis cell for a HHO torch. I want to limit the current used by the cell so that it doesn't break my bridge rectifier by drawing too much current. I want to know how big do my electrodes need to be to draw around 140A. For the anode I'm going to use a plate of 316L steel and the water will contain NaOH.

Sure you don't want to buy a commercial unit? They are available starting at couple hundred dollars, current-limiting is built in.

I'm just doing this for fun and I don't have money to use like this

They need to specify what is considered dangerous tho. Even getting out of the bed is cause you might fall. Plus you wouldn't be encouraging you would just help to make it safer cause I'm still gonna make. Lastly I don't think that building a cell like this is dangerous if you are able to get your hands on everything needed. How am I supposed to ask for help if I don't know anyone with experience?

water will contain NaOH.

This/lye/caustic/corrosive equals "dangerous (among other things)."

Then where should I ask my question?(For me lye isn't even too dangerous since I know how to manage it)

For me lye isn't even too dangerous since I know how to manage it

From:https://www.tn.gov/health/cedep/env... concentrations,lead to permanent lung damage.

Contact with very high concentrations of sodium hydroxide can cause severe burns to the eyes, skin, digestive system or lungs, resulting in permanent damage or death. Prolonged or repeated skin contact may cause dermatitis. Repeated inhalation of sodium hydroxide vapor can lead to permanent lung damage.

However, we do NOT know you well enough to share YOUR confidence in yourself; couple months, meaningful posts on other topics, things may change.

As has been mentioned, we know nothing about you or your level of experience in the many aspects of this project. Also, please keep in mind that even if you are a very experienced person (which I doubt), our advice to you could be read by an inexperienced clueless person in the future and used to hurt themselves trying to duplicate the project.

You are not trying hard enough. Almost always the best way to proceed on such a project is to find a local Mentor who can help you in-person and who can understand your level of experience in the various aspects of the project. Please try harder to find that local Mentor, instead of trying to find advice on the Internet (where we can never know your level of experience).
