Palladium is a chemical element with symbol Pd and atomic number 46.
- Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, which react hydrogen with oxygen to produce electricity, heat, and water.
- In pharmacy, palladium has also found a role in blood glucose testing, as a component of the electrodes used in blood testing meters. Glucose in the blood sample is oxidised by glucose dehydrogenase contained on the test strip, causing a corresponding reduction of a hexacyanoferrate mediator.
- Like other platinum-group metal, bulk Pd is quite inert. Although contact dermatitis has been reported, data on the effects are limited. It has been shown that people with an allergic reaction to palladium also react to nickel, making it advisable to avoid the use of dental alloys containing palladium on those so allergic.
