A radio frequency waveguide communication system includes a controller configured to output a radio frequency signal, and at least one connected node configured to output a node signal indicative of monitored parameter of a machine. The radio frequency waveguide communication system includes a waveguide and a radio frequency interface module. The waveguide is in signal communication with the controller and is configured to guide the radio frequency signal toward the at least one connected node. The radio frequency interface module is configured to establish signal communication between the controller and the at least one connected node, and includes at least one detachable portion configured to detach from the at least one waveguide.

A heat exchanger includes an inlet header, an outlet header and a plurality of flat, multi-channel heat exchange tubes extending therebetween. A longitudinally extending member divides the interior of the header into a first chamber on one side thereof for receiving a fluid and a second chamber on the other side thereof. A plurality of multi-channel heat exchange tubes extend between the headers with the respective inlet end of each heat exchange tube passing into the second chamber of the inlet header. Fluid passes through a series of longitudinally spaced openings in the longitudinally extending member for distribution to the inlets to the channels of the multi-channel heat exchange tubes. The fluid may undergo expansion as it passes through the openings.

A burner assembly includes a catalyzed burner for combusting an anode exhaust stream from a polymer electrolyte membrane (PEM) fuel cell power plant. The catalysts coated onto the burner can be platinum, rhodium, or mixtures thereof. The burner includes open cells which are formed by a lattice, which cells communicate with each other throughout the entire catalyzed burner. Heat produced by combustion of hydrogen in the anode exhaust stream is used to produce steam for use in a steam reformer in the PEM fuel cell assembly. The catalyzed burner has a high surface area wherein about 70&#x2013;90% of the volume of the burner is preferably open cells, and the burner has a low pressure drop of about two to three inches water from the anode exhaust stream inlet to the anode exhaust stream outlet. The burner assembly operates at essentially ambient pressure and at a temperature of up to about 1,700&#xb0; F. (927&#xb0; C.). The burner assembly can combust anode exhaust during normal operation of the fuel cell assembly. The burner assembly also includes an adjunct burner which can combust gasoline or anode bypass gas (the latter of which is a reformed fuel gas which is tapped off of the fuel cell stack fuel inlet line) during startup of the fuel cell power plant. Once start up of the fuel cell power plant is achieved, the burner assembly will need only combustion of the anode exhaust by the catalytic burner to produce steam for the reformer.
