    Abstract: A system for and method of electrochemical testing of fuel cells, such as solid membrane fuel cells, is presented. The system and method allow for non-destructive testing of one or more solid membrane fuel cells. In particular, the system and method allow for testing a working first fuel cell in a testing fixture. The first fuel cell may be removed from the testing fixture without substantial damage to the first fuel cell and replaced by a second fuel cell. The second fuel cell may be electrochemically tested, removed without substantially damaging it, and the process repeated with additional fuel cells.

    Abstract: A power system with a fuel cell array (4) is integrated with power, conversion and control circuitry (6, 8) forming an assembly on a single chip (2). The power system may include mounted discrete components or flip chips. The power transistors (10) may be built with contacts on both top and bottom of the chip, where the large area on the bottom allows for high power dissipation and current densities. Electrical connections are made be­tween the components by etched runs or integrated layers, as is typically found in inte­grated circuits. The control functions include controlling the gas flowing in the fuel cell channels in response to the power supplied. Temperature and pressure may be measured and used to optimize the power system operation.

    Abstract: A fuel cell power plant comprises a fuel cell stack (1) constituted by aplurality of fuel cells which perform electric power generation by means of areaction of hydrogen and oxygen. A controller (16) determines whether or notmoisture inside the fuel cell stack (1) is frozen, and if the moisture is frozen,the controller (16) causes the fuel cell stack (1) to perform intermittent electricpower generation via an inverter (27) while continuing to supply oxygen to thefuel cell stack (1). The fuel cell stack (1) generates heat as a result of theelectric power generation, whereby moisture is generated in a cathode (9).During the periods in which electric power generation is not performed, theoxygen which is supplied to the cathode (9) of the fuel cells scavenges thegenerated moisture, thereby ensuring the supply of oxygen to the cathode (9)during electric power generation.
