Abstract: An air-cooled electronics module is disclosed. The air-cooled electronics module includes a housing and a heat exchanger disposed within the housing and separating the housing into a first portion and a second portion. The air-cooled electronics module also includes one or more electronic components disposed within the first portion, and one or more additional electronic components disposed within the second portion. The air-cooled electronics module further includes at least one fan configured to blow air into the second portion. The air in the first portion is substantially stagnant.

Abstract: An optical detection system for detecting undesirable constituents in a fuel cell system includes a sensing material configured to change color in the presence of the undesirable constituents and at least one sensor configured to register the change in color of the sensing material. The sensor is coupled to a corresponding light source. The sensing material, the sensor and the light source are enclosed in a housing.

Abstract: A sorbent bed assembly, a fuel cell system including the sorbent bed assembly, and methods of using the same. The sorbent bed assembly includes sorbent beds disposed in a stack, such that the sorbent beds extend lengthwise in a non-vertical direction, and conduits configured to fluidly connect the sorbent beds. One or more of the sorbent beds may also include a housing, a removable cartridge disposed in the housing and comprising a sorbent material configured to purify the fuel, and a support configured to prevent the fuel from bypassing the cartridge when the fuel flows through the housing.

Abstract: A roof cap assembly for a fuel cell system includes a housing, and a cover assembly disposed on the housing and configured to move between a first position and a second position. The cover assembly includes a cover comprising a first opening and a second opening, and a door connected to the cover and configured to selectively open and close the second opening. When the cover assembly is in the first position, the door closes the second opening, such that the reaction exhaust and the cabinet exhaust are directed through the first opening. When the cover assembly is in the second position, the door opens the second opening, such that the cabinet exhaust is directed through first opening and the reaction exhaust is directed through the second opening.

Abstract: A pad for a fuel cell system includes a base having an upper surface, a separator disposed on the upper surface of the base, frames disposed on the separator and configured to support modules of the fuel cell system, and plumbing disposed between the upper surface of the base and the frames, and connected to the fuel cell modules. The separator is configured to space apart the frames and the upper surface of the base. The base may include modular sections that may be arranged in a linear configuration, a rectangular configuration, an orthogonal configuration, or a stepped configuration.
