Abstract: An anode inlet unit for a split fuel cell stack or two fuel cell stacks having two anode inlets. The anode inlet unit has particular application for a small vehicle that requires less power. In one embodiment, the anode inlet unit only includes three injectors. Two of the injectors provide flow control for the hydrogen gas to the two anode inlets to provide the desired turn-down ratio. For a split stack design, the two injectors may provide flow-shifting where the injection of hydrogen gas into the sub-stacks is alternated. The other injector injects a small amount of hydrogen into the cathode side of the fuel cell stack at system start-up to quickly increase the operating temperature of the system. Additionally, two valves can be provided in the unit that receive a flow of air to purge the anode side of the stack for system shut-down.

The positive electrode material is a conductive composite oxide represented by the general formula AgxNiyO2, in which X/Y is greater than 1 and does not exceed 1.9, and by the general formula AgxNiyMzO2, in which M represents at least one of Cu and Bi, X/(Y+Z) is greater than 1 and does not exceed 1.9, and Z does not exceed 0.4. These conductive oxides contain almost no free Ag2O and have a crystal structure similar to that of AgNiO2. As a result, the excess Ag—Ni oxide is conductive and has a high discharge capacity.
