Abstract

A fuel cell powered vehicle is disclosed having a fuel storage tank, wherein the fuel tank is disposed on an undercarriage of the vehicle and has a substantially ovoid shape to militate against interference with a function of a suspension system of the vehicle.

Claims (27)

1 . A fuel tank comprising:

an outer wall forming a cavity for housing a compressed fuel;

a first portion having a first volume;

a second portion having a second volume substantially equal to the first volume; and

a third portion disposed between said first portion and said second portion and having a volume greater than the volume of each of said first portion and said second portion, the fuel tank adapted to be disposed on an undercarriage of a fuel cell powered vehicle and minimize an interference with a suspension system of the vehicle.

2 . The fuel tank of claim 1 , wherein said outer wall has a substantially ovoid shape.

3 . The fuel tank of claim 2 , wherein said outer wall has one of pointed ends and rounded ends.

4 . The fuel tank of claim 1 , wherein the fuel is a liquid.

5 . The fuel tank of claim 1 , wherein the compressed fuel is a compressed gas.

6 . The fuel tank of claim 1 , wherein the compressed fuel is hydrogen.

7 . The fuel tank of claim 1 , wherein the outer wall is formed from one of a plastic, a composite, and a metal.

8 . A fuel tank comprising:

a substantially ovoid shaped outer wall, said outer wall forming a cavity for housing a compressed fuel, the fuel tank adapted to be disposed on a fuel cell powered vehicle and minimize an interference with a suspension system of the vehicle.

9 . The fuel tank of claim 8 , wherein the outer wall has a substantially ovoid cross-sectional shape with one of a rounded and a pointed end.

10 . The fuel tank of claim 9 , wherein said outer wall has one of pointed ends and rounded ends.

11 . The fuel tank of claim 8 , wherein the fuel is a liquid.

12 . The fuel tank of claim 8 , wherein the compressed fuel is a compressed gas.

13 . The fuel tank of claim 8 , wherein the compressed fuel is hydrogen.

14 . The fuel tank of claim 8 , wherein the outer wall is formed from one of a plastic, a composite, and a metal.

15 . A fuel cell propulsion system comprising:

Fuel cell system, including a stack which includes a plurality of fuel cell plates; and

a fuel tank having an outer wall forming a cavity for housing a compressed fuel, the outer wall having a first portion having a first volume, a second portion having a second volume substantially equal to the first volume, and a third portion disposed between said first portion and said second portion and having a volume greater than the volume of each of said first portion and said second portion, the fuel tank adapted to be disposed on an undercarriage of a fuel cell powered vehicle and minimize an interference with a suspension system of the vehicle.

16 . The fuel cell propulsion system of claim 15 , wherein the outer wall has a substantially ovoid cross-sectional shape having rounded ends.

17 . The fuel cell propulsion system of claim 16 , wherein said outer wall has one of pointed ends and rounded ends.

18 . The fuel cell propulsion system of claim 15 , wherein the outer wall has a substantially ovoid cross-sectional shape having pointed ends.

19 . The fuel cell propulsion system of claim 15 , wherein the fuel is a liquid.

20 . The fuel cell propulsion system of claim 15 , wherein the outer wall is formed from one of a plastic, a composite, and a metal.
