摘要： The oxidant inlets of the reactant gas flow field grooves (41) of a fuel cell (11) which suffers a crossover between the fuel and oxidant flow fields, due to a leak in the seals, the maxtrix or the membrane of the fuel cell, are blocked with a liquid (50) which cures in place, hot glue, two-part epoxy, or fluoroelastomers. This prevents heating as a result of combusting fuel with oxygen near the site, which avoids excessive heating and damaging of successive fuel cells. As a result, a fuel cell power plant (8) can continue to operate with only a minor loss of voltage and power, thereby avoiding the need to tear down the stack by loosening the tie-bolts. Voltage and hydrogen levels may be used to detect the crossover. The particular cell (11) with the leak can be determined by voltage or hydrogen monitoring, or by immersing the stack in a liquid while applying gas to the fuel inlet of the stack.
摘要翻译：燃料电池（11）的反应气体流场槽（41）的氧化剂入口由于燃料电池的密封件，最大或者膜的泄漏而在燃料和氧化剂流场之间产生交叉，被固化的液体（50）封闭，热胶，两部分环氧树脂或含氟弹性体。这可以防止由于在现场附近的氧气燃烧燃料而导致的加热，这避免了过度的加热和连续的燃料电池的损坏。结果，燃料电池发电厂（8）可以继续工作，只有轻微的电压和功率损失，从而避免了通过松开连接螺栓来拆下堆叠的需要。电压和氢气水平可用于检测交叉。具有泄漏的特定电池（11）可以通过电压或氢气监测来确定，或者通过将烟囱浸入液体中同时将气体施加到堆的燃料入口来确定。

摘要： Fuel cell stack assemblies (15, 16) connected in parallel through related power control portions (39, 40; 60, 61 ) of a system power converter (41 ) supply power to a common grid (22) or non-grid load (58) on an equal or near-equal current basis. Power command to one portion is one-half the total power (P*) minus a function (46) of the difference (45) in current from the stack assemblies. The other portion power command (P1*) for a utility grid (22) is the difference between the total power and the power command (P2*) to the first stack assembly. For a non-grid load, one portion (61 ) controls the load voltage, the other portion command (P2*) causes substantially equal currents. Altering (33b) actual current signals results in the cell stack assemblies providing different currents. A failed stack assembly is disconnected from the load and reactant; the non-failed assembly having an appropriate power command.

摘要： A reformer system (11) having a hydrodesulfurizer (12) provides desulfurized natural gas feedstock to a catalytic steam reformer (16), the outflow of which is treated by a water gas shift reactor (20) and optionally a preferential CO oxidizer (58) to provide reformate gas (28, 28a) having high hydrogen and moderate carbon dioxide content. To avoid damage to the hydrodesulfurizer from overheating, any olefins in the non-desulfurized natural gas feedstock (35) are reacted (38) with hydrogen (28, 28a; 71) to convert them to alkanes (e.g., ethylene and propylene to ethane and propane) in a hydrogenator (38) cooled (46), below a temperature which would damage the hydrogenator, by evaporative cooling with pressurized hot water (42). Hydrogen for the desulfurizer and the olefin reaction may be provided as recycle reformate (28, 28a) or from a mini-CPO (67), or from other sources.

摘要： A sheet of fiber carbon paper (9) is advanced from a first roll on a spindle (11) around a roller (14) to a second roll around a spindle (15). Bending of the sheet of fiber carbon paper around the roller (14) causes fibers that are prone to disentangle to protrude outwardly from the surface and are shaved off by a razor-sharp edge (17) affixed to a stationary point (18). Alternatively, carbon fiber elements, such as a fuel cell gas diffusion layer (20) may be fixed in an arcuate jig (22) and a razor-sharp edge (31) may revolve along the surface of the element to cut off any protruding fibers.
