Abstract
An alignment system and method for assembling a fuel cell stack. Components of the fuel cell stack have internal alignment features and are aligned to a predetermined orientation during assembly. The system and method allow fuel cell stacks to be assembled within high tolerance levels while improving access to each component during assembly. Additionally, the system and method can provide additional rigidity to a fuel cell stack.
