A system and method is described for a driver circuit used for high speed data transmission in LVDS and CML transceiver device applications. The transceivers are intended to receive a low voltage differential input signal and interchangeably drive a standard LVDS load with a TIA/EIA-644 compliant LVDS signal, and a standard CML load with a standard CML compatible signal. The driver circuit operates at speeds up to 1.36 Gbps, making it compatible with the OC-24 signaling rate for optical transmission. To accomplish this, the driver uses a mixed combination of voltage and current mode drive sections in the output circuit when coupled to LVDS loads, and when the driver is coupled to CML loads, operates purely in a current mode using only the current mode drive section. MOS transistors and a current source are used in the current mode switch portion to switch the drive with a constant current at the high speeds, and NPN transistors in the voltage mode output portion provide variable impedance for the output circuit. A common mode compensation circuit using a feedback voltage from the load generates a compensation signal for variable impedance control of the NPN transistors to yield a regulated voltage for the common mode dc voltage.

A fuel cell system, which may be powering a vehicle propulsion system (159), includes a fuel cell power plant having a stack (151) including a plurality of fuel cells (12), each having a cathode (19) and anode (17) separated by a membrane (16), and an air pump (174) connected to reactant air flow fields through a diverter valve (172). A controller (185) is responsive to normal and high demand to cause the diverter valve to allow air to flow from the pump to the reactant air flow fields, and is responsive to low demand to cause said diverter valve to divert air directly into ambient so that it does not reach the cathode, thereby to reduce open circuit voltage conditions that promote degradation of the cathode, and to prevent excessive performance decay. An auxiliary load (220) can be in the diverted air flow, either ahead of or after the diverter valve. Energy storage (200, 201) works with the vehicle propulsion system.
