<p>A method for increasing the reliability of an electrolyzer cell stack includes providing multiple electrolyzer cell stacks. Each electrolyzer cell stack includes multiple cells (100) separated by electrically conductive interconnects (112a). The method may further include generating, using an external power source, an electrical current through each of the electrolyzer cell stacks to produce a fuel. The method may further include electrically connecting an interconnect (112a) of a first electrolyzer cell stack to an interconnect (112a) of a second electrolyzer cell stack located at a substantially equivalent electrical potential. This allows current to flow from one electrolyzer cell stack to another in the event a cell fails or creates a point of high resistance.</p>
