Modular architecture for fuel cell powered transport refrigeration

A transport refrigeration system comprising:

• a refrigeration unit for conditioning an area;
• a plurality of replaceable modules, the plurality of replaceable modules including at least one of a quick connect electrical interface and a quick connect mechanical interface and being independently removable from the refrigeration unit;
• a power system operably coupled to the refrigeration unit, the power system including at least one fuel cell and a fuel source, wherein the at least one fuel cell of the power system is packaged into a first replaceable module of the plurality of replaceable modules and the fuel source is separate from the first replaceable module;
• and
• an exhaust gas system operable to condition an exhaust gas output from the at least one fuel cell, at least a portion of the exhaust gas system being packaged into a second replaceable module of the plurality of replaceable modules.
