Abstract:
1. Electrochemical energy source, comprising a plurality of fuel cells, wherein each fuel cell comprises: a first current collector coupled to a negative electrode, a fuel source connected to said negative electrode, a second current collector coupled to a positive electrode, an oxidant source connected to said positive electrode, and an ion-conducting electrolyte located between said negative electrode and said positive electrode, characterized in that the electrochemical energy source has a curved, planar geometry, wherein at least one fuel cell is stacked by a polymer material riveted through cavities formed in the positive electrode, the negative electrode, and the electrolyte, and wherein the electrochemical energy source comprises a lamination of at least one of said positive electrodes and said negative electrodes, characterized in that the lamination has a curved shape such that the lamination is situated in one curved plane and the resulting electrochemical energy source has a corresponding curved surface.
