| 摘要 |
The device (10a) has a redox unit (12a) performing redox reaction with consumption and/or production of first gas i.e. hydrogen gas, and/or second gas i.e. oxygen gas. The redox unit comprises a gas purification unit (20a) for freeing the first gas of contamination by the second gas and/or freeing the second gas of contamination by the first gas. The gas purification unit comprises a catalyst unit (22a) for catalyzing reaction of oxygen gas and hydrogen gas into water. The catalyst unit includes catalyst elements (26a, 28a) comprising platinum metal partly. The redox unit is configured as a fuel cell i.e. alkaline fuel cell (16a), an electrolyzer for producing hydrogen gas and/or oxygen gas or a fuel cell-electrolyzer pair. An independent claim is also included for a method for operating a redox device in closed operation. |
