## Abstract

Disclosed are packaging systems and method 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.

## Claims

### Claim 1

A device for storing or transporting oxidatively degradable foodstuff, comprising:
a sealable tote usable for storing or transporting the oxidatively degradable foodstuff;
a fuel cell having at least a cathode having a cathode inlet in gaseous communication with an inside of the tote, the cathode configured to consume oxygen inside the tote and thereby extract oxygen from the inside of the tote, wherein the fuel cell is contained internal to the tote; and
a hydrogen source in gaseous communication with the fuel cell anode.

### Claim 2 (depends on 1)

The device of claim 1, wherein the sealable tote comprises a rigid tote.

### Claim 3 (depends on 2)

The device of claim 2, wherein the rigid tote comprises a refrigerator.

### Claim 4 (depends on 1)

The device of claim 1, further comprising a carbon dioxide remover.

### Claim 5 (depends on 4)

The device of claim 4, wherein the carbon dioxide remover comprises hydrated lime, activated carbon, lithium hydroxide or metal oxides.

### Claim 6

A device for storing or transporting oxidatively degradable foodstuff, comprising:
a sealable tote usable for storing or transporting the oxidatively degradable foodstuff;
a fuel cell having at least a cathode having a cathode inlet in gaseous communication with an inside of the tote, the cathode configured to consume oxygen inside the tote and thereby extract oxygen from the inside of the tote; and
a hydrogen source in gaseous communication with the fuel cell anode,
wherein the fuel cell is configured to react hydrogen from the hydrogen source with oxygen located in the tote to consume the oxygen located in the tote wherein the fuel cell is contained internal to the tote.

### Claim 7 (depends on 6)

The device of claim 6, wherein the sealable tote comprises a rigid tote.

### Claim 8 (depends on 7)

The device of claim 7, wherein the rigid tote comprises a refrigerator.
