Abstract:
1. A fuel cell comprising: a first cylindrically configured outer shell section containing a fuel processor that generates fuel gas and having an end forming a negative terminal; and a second cylindrically configured outer shell section axially aligned and secured to said first outer shell section and having an end forming a positive terminal and positioned linearly opposite the end of the first cylindrically configured outer shell section forming the negative terminal to form together a cylindrical battery cell such that the ends of the cylindrical battery cell form the respective negative and positive terminals, said second outer shell section containing therein a fuel cell having electrodes forming an anode and cathode, an ion exchange electrolyte positioned between said electrodes, wherein said fuel cell receives fuel gas generated from the fuel processor and an oxidant gas through the second outer shell section for generating an electric current, wherein said first outer shell section comprises a conductive shell member operatively connected to said anode, and an insulator over at least a portion of said conductive shell member and leaving an end portion exposed and forming the negative terminal, and a conductive disk terminal positioned at an end of the second outer shell section and operatively connected to said cathode and forming the positive terminal, and an anode extension as a conductive member extending from the anode of the fuel cell contained in the second cylindrically configured outer shell section and extending from the fuel cell into contact with the conductive shell member and provide electrical potential at the negative terminal.
