Abstract
A fan flow sensor for a hydrogen generating proton exchange member electrolysis cell includes a switching device and a sail slideably disposed on the switching device. The sail is configured to actuate the switching device in response to an airflow from a fan. The switching device may be actuatable in response to a magnet disposed on the sail.
