1. A proton exchange membrane fuel cell stack, comprising: multiple serially arranged proton exchange membrane fuel cell modules;an individual proton exchange membrane fuel cell module including: a frame having generally opposing first and second major surfaces and an outer perimeter defining surface and an inner cavity defining surface each of which extend between the first and second major surfaces to define a width of the frame;a current collecting separator plate mounted on the first major surface of the frame;a proton exchange membrane having an anode side and a cathode side;a first electrically conductive porous layer juxtaposed relative to the anode side;a second electrically conductive porous layer juxtaposed relative to the cathode side; and,an electrically conductive heat sink juxtaposed relative to the second electrically conductive porous layer,wherein the frame width is sufficient to nestably receive the proton exchange membrane, the first and second electrically conductive porous layers, and the electrically conductive heat sink between the first and second major surfaces effective that both the second major surface of the frame and the electrically conductive heat sink contact a current collecting separator plate associated with a frame of an individual adjacent proton exchange membrane fuel cell module; andwherein the multiple serially arranged proton exchange membrane fuel cell modules are associated against one another with an anode side of the individual proton exchange membrane fuel cell module positioned adjacent to a cathode side of the individual adjacent proton exchange membrane fuel cell module to form the proton exchange membrane fuel cell stack. 2. The proton exchange membrane fuel cell stack of claim 1, wherein the inner cavity defining surface is configured to automatically align the proton exchange membrane, the first and second electrically conductive porous layers, and the electrically conductive heat sink, and wherein the frame further includes self-alignment features configured to automatically align the frame to the frame of the individual adjacent proton exchange membrane fuel cell module. 3. A proton exchange membrane fuel cell stack, comprising: adjacent first and second serially arranged proton exchange membrane fuel cell modules;each of the first and second proton exchange membrane fuel cell modules including: a frame having an inside and an outside peripheral edge, and first and second sides, and wherein the inside peripheral edge defines an internal cavity relative to the second side and wherein the frame is generally open at opposing ends to create an air passageway which extends between the inside and outside peripheral edges and which communicates with the internal cavity thereof;a current collecting separator plate mounted on the first side of the frame;wherein the first proton exchange membrane fuel cell module includes an electrically conductive heat sink that is positioned within the internal cavity effective that both the second side of the frame and the electrically conductive heat sink contact a current collecting separator plate of the second proton exchange membrane fuel cell module; andwherein the adjacent first and second serially arranged proton exchange membrane fuel cell modules are arranged with an anode side of the first proton exchange membrane fuel cell module positioned against a cathode side of the second proton exchange membrane fuel cell module the proton exchange membrane fuel cell stack.
