Electrochemical power systems of modular design are provided. In accordance with one embodiment of the present invention, an electrochemical power system is provided comprising a container, at least one container reactant port, at least one container electrical power output port, module mounting hardware within the container, and a set of fuel cell modules within the container. Each of the fuel cell modules is mounted within the container via the module mounting hardware. Each of the fuel cell modules comprises at least one modular reactant port and at least one modular electrical power output port. The fuel cell modules and the module mounting hardware are configured to (i) place the modular reactant ports in communication with the container reactant port, (ii) place the modular electrical power output port in communication with the container electrical power output port, and (iii) permit replacement of a single fuel cell module substantially free of interference with remaining modules of the set of fuel cell modules.
