Abstract

A combustion tool fuel cell is provided having enhanced low temperature operation, including a fuel composition comprising at least one hydrocarbon component with a total vapor pressure equal or above 95 psig at 21° C.

First claim

The invention claimed is:

1. A combustion tool fuel cell having enhanced low temperature operation, said combustion tool fuel cell comprising:
a first compartment enclosing a fuel composition having a total vapor pressure equal to or above 95 psig at 21° C., said fuel composition consisting of a single hydrocarbon component selected from the group consisting of propylene and propane; and
a second compartment enclosing a combustion tool fuel cell propellant, wherein said combustion tool fuel cell propellant has a total vapor pressure equal to or above 140 psig at 21° C., said combustion tool fuel cell propellant comprising ethane, acetylene, or a mix thereof;
wherein said second compartment is separate from said first compartment;
wherein the combustion tool fuel cell is configured for connection to a fuel delivery system of a combustion tool to provide enhanced low temperature operation.

2. The combustion tool fuel cell of claim 1 , wherein the single hydrocarbon component is propylene.

3. The combustion tool fuel cell of claim 1 , wherein the single hydrocarbon component is propane.

4. The combustion tool fuel cell of claim 1 , wherein the combustion tool fuel cell propellant comprises ethane.

5. The combustion tool fuel cell of claim 1 , wherein the combustion tool fuel cell propellant comprises acetylene.

6. The combustion tool fuel cell of claim 1 , wherein the combustion tool fuel cell propellant comprises a mix of ethane and acetylene.
