Hydrogen Control for Enclosed Anodizing

I am looking for information to properly scale the ventilation rate for an enclosed aluminum anodize tank. The concern is buildup of hydrogen during processing. How do I determine the minimum flow to keep hydrogen below 10% of the Lower Explosive Limit?

Faraday's Law of Electrolysis should work here. Each Faraday of electricity (96,485 amp-seconds) should release one gram equivalent weight of hydrogen. Ted Mooney, finishing.com
