hydrogen peroxide oxygen supply

As much of a question as an idea

This is basically an alternative to storing oxygen in gas tanks.

Hydrogen peroxide would be stored in a tank with a catalyst dipper (e.g. platinum) that can be immersed to control the rate of oxygen production.

Even relatively low concentrations of H2O2 create a surprising amount of oxygen, e.g. 6% concentration H2O2 produces 20 liters of oxygen for each litre of hydrogen peroxide decomposed (according to wikipedia).

Of course this would create far less oxygen compared with a regular gas tank of equal size, but there may be some situations where a gas tank is not desirable. For example it would be relatively easy to refill a tank with hydrogen peroxide compared to filling a tank with oxygen. Also, it might be safer in some situations.

Although I have classified this idea in sport:water:underwater I doubt this would be a suitable application; I just thought I may as well stick this idea with the scuba tank ideas.

       Baked. Used in submarines for decades, widely known to exist. Sodium peroxide systems too.

       not to mention the use on space stations and the applications in atmospheric recycling.
