Disclosed are packaging systems and methods useful in extending the storage-life of foodstuff such as fresh fish. The packaging systems and methods can be used to transport or store the foodstuff for an extended period of time. The packaging systems preferably use a fuel cell to maintain a reduced oxygen level in the environment surrounding the foodstuff.

1. A packaging module useful in transporting and/or storing of carbon dioxide absorbing oxidatively-degradable foodstuffs which comprises: a) a pressure-stable sealed tote of limited oxygen permeability and a defined headspace;b) a carbon dioxide absorbing oxidatively-degradable foodstuff;c) a fuel
1. A packaging module useful in transporting and/or storing of carbon dioxide absorbing oxidatively-degradable foodstuffs which comprises: a) a pressure-stable sealed tote of limited oxygen permeability and a defined headspace;b) a carbon dioxide absorbing oxidatively-degradable foodstuff;c) a fuel cell capable of converting hydrogen and oxygen into water, wherein the fuel cell does not require an external power source to convert the hydrogen and oxygen into water;d) a hydrogen source; ande) further wherein the initial headspace occupies at least 30 volume percent of the tote and the gas in the headspace comprises at least 99 vol. percent gases other than oxygen;an anode of the fuel cell is in communication with the hydrogen source and a cathode inlet of the fuel cell is in communication with the environment in the tote; andin a presence of the oxygen in the environment in the tote, protons and electrons are generated by the anode, and the protons interact with the oxygen present at the cathode to generate water and to remove the oxygen from the environment in the tote. 2. The packaging module of claim 1, wherein the gaseous headspace comprises at least about 90% carbon dioxide. 3. The packaging module of claim 1, wherein the gaseous headspace comprises from about 30% to about 35% of the total internal volume of the tote. 4. The packaging module of claim 1, wherein the gaseous headspace comprises about 35% of the total internal volume of the tote. 5. The packaging module of claim 1, which further comprises a holding element which maintains a hydrogen source internal to the tote. 6. The packaging module of claim 5, wherein the holding element for the hydrogen source in the tote is a box which holds the hydrogen source and the fuel cell internal to the tote. 7. The packaging module of claim 1, wherein the packaging module does not contain a gaseous source to maintain positive pressure within the packing module during transport or storage. 8. The packaging module of claim 1, wherein the foodstuff is fish. 9. The packaging module of claim 8, wherein the fish is fresh fish selected from the group consisting of salmon, tilapia, tuna, shrimp, trout, catfish, sea bream, sea bass, striped bass, red drum, pompano, haddock, hake, halibut, cod, and arctic char. 10. The packaging module of claim 9, wherein the fresh fish is salmon or tilapia. 11. The packaging module of claim 1, wherein the hydrogen source is selected from the group consisting of a bladder hydrogen source or a rigid container hydrogen source. 12. The packaging module of claim 1, further comprising a fan. 13. The packaging module of claim 12, wherein the fan is powered by the fuel cell. 14. The packaging module of claim 1, wherein said tote consists of a flexible, collapsible or expandable material which does not puncture when collapsing or expanding. 15. A packaging module useful in transporting and/or storing of carbon dioxide absorbing oxidatively-degradable foodstuffs which comprises: a) a pressure-stable sealed tote of limited oxygen permeability and a defined headspace;b) a carbon dioxide absorbing oxidatively-degradable foodstuff;c) a fuel cell capable of converting hydrogen and oxygen into water; andd) a hydrogen source, e) wherein the initial headspace occupies at least 30 volume percent of the tote and the gas in the headspace comprises at least 99 vol. percent gases other than oxygen, and f) wherein the hydrogen source is a gaseous mixture comprising carbon dioxide and less than 5% by volume hydrogen. 16. A system useful in transporting and/or storing of carbon dioxide absorbing oxidatively-degradable foodstuffs which comprises one or more packaging modules, each packing module comprising: i) a pressure-stable sealed tote of limited oxygen permeability and a defined headspace;ii) a carbon dioxide absorbing oxidatively-degradable foodstuff;iii) a fuel cell capable of converting hydrogen and oxygen into water, wherein the fuel cell does not require an external power source to convert the hydrogen and oxygen into water;iv) a hydrogen source; andv) further wherein the initial headspace occupies at least 30 volume percent of the tote and the gas in the headspace comprises at least 99 vol. percent gases other than oxygen;an anode of the fuel cell is in communication with the hydrogen source and a cathode inlet of the fuel cell is in communication with the environment in the tote; andin a presence of the oxygen in the environment in the tote, protons and electrons are generated by the anode, and the protons interact with the oxygen present at the cathode to generate water and to remove the oxygen from the environment in the tote. 17. The system of claim 16, wherein said tote consists of a flexible, collapsible or expandable material which does not puncture when collapsing or expanding. 18. The system of claim 16, further comprising a box holding element which holds the hydrogen source and the fuel cell internal to the tote.
