NOVELTY - A fuel cell system (50) comprises storage system (58), reactor (56), fuel cell (52), and catalytic combustor (54). The storage system stores and releases a liquid carrier comprising hydrogen. The reactor receives liquid carrier to catalytically dehydrogenate liquid carrier to produce a hydrogen flow. The fuel cell is in fluid communication with the reactor for receiving the hydrogen flow from the reactor and for electrochemically reacting the hydrogen flow with an oxidant to produce electricity and an anode exhaust. The catalytic combustor is in fluid communication with the fuel cell.    USE - For powering an automobile or other vehicles.    ADVANTAGE - The fuel cell system enables utilization of liquid carrier storage of hydrogen without requiring independent heat generation to release the hydrogen from the storage tanks. The fuel cell system enables cold start of the PEM fuel cell and a hydrogen storage system. The fuel cell system solves cold start problem.    DETAILED DESCRIPTION - A fuel cell system comprises storage system, reactor, fuel cell, and catalytic combustor. The storage system stores and releases a liquid carrier comprising hydrogen. The reactor receives liquid carrier to catalytically dehydrogenate liquid carrier to produce a hydrogen flow. The fuel cell is in fluid communication with the reactor for receiving the hydrogen flow from the reactor and for electrochemically reacting the hydrogen flow with an oxidant to produce electricity and an anode exhaust. The catalytic combustor is in fluid communication with the fuel cell for receiving portion of the anode exhaust and for catalytically reacting the anode exhaust to produce an off gas having an elevated temperature that is greater than the temperature of the anode exhaust. The heat from the off gas is used to heat the reactor to catalytically dehydrogenate the liquid carrier to produce the hydrogen. The fuel cell is a polymer electrolyte membrane (PEM) fuel cell. The anode exhaust comprises less than about 15% by volume of hydrogen. The temperature of the anode exhaust is 60-150, preferably less than 150degreesC. The temperature of the off as is greater than 150degreesC. The temperature of the off as is 150-900degreesC. The catalytic combustor comprises a combustion catalyst. The storage system includes a tank having a flexible diaphragm that separates the liquid carrier comprising hydrogen from hydrogen-depleted liquid carrier.
