NOVELTY - System comprises: (a) a fuel cell having a fuel cell inlet to receive preheated intake gas and a fuel cell outlet to release hot fuel cell exhaust; (b) a heat exchanger (HX) having a HX cold-side inlet, a HX cold-side outlet, a HX hot-side inlet and a HX hot-side outlet; and (c) a thermoelectric generator (TE) to generate electric energy based on a temperature differential between a TE cold-side and a TE hot-side.    USE - The systems and methods are used for generating electric power.    ADVANTAGE - Electric power is generated using a power cogeneration system, which uses both a fuel cell and a thermoelectric generator to generate electric power. The fuel cell may generate electric power based on a chemical reaction between a fuel and an oxidizer. The fuel cell may also generate heat as a byproduct of the chemical reaction. The thermoelectric generator may generate additional electric power based on a temperature differential between an intake fluid provided to the fuel cell (e.g., oxidizer or fuel) and hot exhaust (from an anode or a cathode) of the fuel cell.    DETAILED DESCRIPTION - System comprises: (a) a fuel cell having a fuel cell inlet to receive preheated intake gas and a fuel cell outlet to release hot fuel cell exhaust; (b) a heat exchanger (HX) having a HX cold-side inlet, a HX cold-side outlet, a HX hot-side inlet and a HX hot-side outlet; and (c) a thermoelectric generator (TE) to generate electric energy based on a temperature differential between a TE cold-side and a TE hot-side, where the TE comprises: (i) a TE cold-side inlet to receive intake gases; (ii) a TE cold-side outlet coupled to the HX cold-side inlet; (iii) a TE hot-side inlet coupled to the fuel cell outlet to receive the hot fuel cell exhaust; and (iv) a TE hot-side outlet coupled to the HX hot-side inlet. INDEPENDENT CLAIMS are included for:    (1) a platform comprising: (a) a fuel cell to generate electric power; (b) a TE to generate additional electric power using a temperature differential between fuel cell exhaust from the fuel cell and fuel cell intake gases; and (c) an HX to preheat the fuel cell intake gases before the fuel cell intake gases are provided to the fuel cell by recovering heat from the fuel cell exhaust after the fuel cell exhaust has passed through the TE; and    (2) a method comprising: (a) generating electric power using a fuel cell; (b) generating additional electric power using a TE by routing exhaust from the fuel cell to a hot side of the TE, and routing fuel cell intake gases to a cold side of the TE; and (c) preheating the fuel cell intake gases.
