Abstract
Abstract A power supply includes a fuel cell stack, a thermoelectric module and a burner module. The fuel cell stack generates a primary source of electricity and secondary source of heat. The thermoelectric module generates a secondary source of electricity. The burner module is juxtaposed to the fuel cell stack and the thermoelectric module, to provide primary heat to the system and to generate a temperature differential across the thermoelectric module, and to pre-heat a fuel and an oxidant for the fuel cell stack. The burner module is regulated to maintain a given system temperature, or when needed by the thermoelectric generator for secondary power generation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
62 words
A method of generating heat and electrical energy, comprising the steps of supplying a first fuel to a burner for generating a temperature differential across a thermoelectric element generating electricity for secondary power, and for pre-heating a second fuel, said pre-heating comprising primary heat, supplying said second fuel to a fuel cell stack for generating electricity for primary power and secondary heat.
Claim 2
Independent Claim
62 words
A method of generating heat and electrical energy, comprising the steps of supplying a first fuel to a burner for generating a temperature differential across a thermoelectric element generating electricity for secondary power, and for pre-heating a second fuel, said pre-heating comprising primary heat, supplying said second fuel to a fuel cell stack for generating electricity for primary power and secondary heat.
Claim 3
Dependent Claim
27 words
A method as claimed in claim 1 wherein said method further comprises a step of cooling one side of said thermoelectric element to increase said temperature differential.
Claim 4
Dependent Claim
21 words
A method as claimed in claim 1 wherein said first fuel and said second fuel are supplied from a common source.
Claim 5
Dependent Claim
25 words
A method as claimed in claim 1 wherein said method further comprises a step of regulating said first fuel to maintain an optimal operating temperature.
Claim 6
Dependent Claim
23 words
A method as claimed in claim 1 wherein said method further includes a step of extracting said primary and secondary power and heat.
