Patent ID: 7914294

Claim:
An electrical system for a fuel cell stack, the electrical system comprising: an interface unit; a fuel cell stack; and an electrical connector coupled to the interface unit and the fuel cell stack, including a first contact portion, a second contact portion spaced from the first contact portion, a resilient portion extending between the first contact portion and the second contact portion, the resilient portion having a substantially helical shape, the resilient portion adapted to facilitate relative movement between the first contact portion and the second contact portion, wherein the electrical connector is formed by a pair of conductors having a first contact portion, a second contact portion spaced from the first contact portion, and a resilient portion extending between the first contact portion and the second contact portion, the first contact portions of the conductors forming the first contact portion of the electrical connector, the second contact portions of the conductors forming the second contact portion of the electrical connector, and the resilient portions of the conductors forming the resilient portion of the electrical connector, wherein an insulator is disposed between and insulates the conductors, and wherein the insulator includes a first portion abutting the first contact portions of the pair of conductors, a second portion abutting the second contact portions of the pair of conductors, and a third portion extending between the first portion and the second portion of the insulator, the third portion having a substantially helical shape and abutting the resilient portions of the pair of conductors.
