ABSTRACT:
Uniform compressive stress distribution is applied over the active area of a PEMFC stack to increase the contact area between the electrically conductive components of the stack. This increases fuel cell stack efficiency. Fuel cell stack is constructed as a modular component readily connected with like modules for providing fuel cell stack configurations capable of meeting a wide range of power generation for application to vehicles, including submersible vehicles up to utility power requirements.
