Abstract
An efficient process for the production of nitrogen from air using a fuel cell to provide both electrical power and an oxygen depleted gas stream to a liquefaction apparatus is disclosed. An apparatus for the production of nitrogen incorporating a fuel cell is also disclosed.
Claims1
An apparatus for the production of nitrogen from air, comprising:
- a fuel cell for providing electrical energy and a stream of oxygen depleted, nitrogen enriched cathode exhaust,
- means for liquifying the cathode exhaust to form a mixture of liquid nitrogen and liquid oxygen, and
- means for separating the mixture to produce a stream of nitrogen product and a stream of oxygen by-product.
