Fuel Cell Mechanical Components

A method of making a modular fuel cell system, comprising:

• casting a concrete or geopolymer base material in a mold to form a cast base having a plurality of channels;
• removing the cast base from the mold;
• transporting the cast base from a location of the mold to a location of the fuel cell system;
• placing at least one power module, a fuel processing module and a power conditioning module on the base;
• and
• installing in the channels in the cast base for electrical bus bar conduits, input and output fuel conduits, and at least one water conduit which extend to the system, from the system, or between the modules.
