Is there a fundamental problem with using a high purity H2 generator like this unit on Amazon:

From my research they can produce hydrogen purity and pressure much higher than some more expensive H2 therapy devices. Of couse I am not endorsing breathing high purity hydrogen at a high flow rate but those things can be controlled by any responsible adult, along with combustion avoidance.The higherflow rate would be superior for saturating water and even baths.
