摘要： A fuel cell stack (10) includes a reaction portion (20) having an end cell (12) secured adjacent to a current collector (30). The collector (30) has a sensible heat no greater than a sensible heat of the end cell (12) and an electrical resistivity no greater than 100 micro-ohms centimeters. An insulator (40) is secured adjacent the collector (30) and has a thermal conductivity that is no greater than 0.500 Watts per meter per degree Kelvin. Because of the low sensible heat of the current collector (30) and low rape of heat transfer of the insulator (40), heat does not readily leave the end cell (12) resulting in a rapid heating of the end cell (12), thereby avoiding freezing and accumulation of product water in the end cell (12) during start up in subfreezing conditions.

摘要： A fuel cell system having a stack of proton exchange membrane fuel cells is operated in sub-freezing temperatures by draining any liquid water from the fuel cell water flow passages upon or after the previous shut-down of the stack before freezing can occur, and, thereafter a) starting-up the stack by directing fuel and oxidant reactants into the cell and connecting a load to the stack; b) using heat produced by the stack to increase the operating temperature of the stack to melt ice within the stack; and, c) upon the stack operating temperature reaching at least O'C, circulating anti-freeze through stack coolers to maintain the temperature of the stack low enough to maintain a sufficiently low water vapor pressure within the cells to prevent cell dry out for at least as long as there is insufficient liquid water to circulate through the water flow passages.

摘要： A fuel cell (70) having an anode (72), a cathode (78) and an electrolyte (76) between the anode (72) and the cathode (78) includes a cathode catalyst (80) formed of a plurality of nanoparticles. Each nanoparticle (20) has a plurality of terraces (26) formed of platinum surface atoms (14), and a plurality of edge (28) and corner regions (29) formed of atoms from a second metal (30) - The cathode catalyst may be formed by combining a platinum nanoparticle with a metal salt in a solution. Ions from the second metal react with platinum and replace platinum atoms on the nanoparticle. The second metal atoms at the corner and edge regions of the nanoparticle, as well as at any surface defects, result in a more stable catalyst structure. In some embodiments, the fuel cell (70) is a proton exchange membrane fuel cell and the nanoparticles are tetrahedron- shaped. In some embodiments, the fuel cell (70) is a phosphoric acid fuel cell and the nanoparticles are cubic-shaped.

摘要： A method of producing stabilized platinum nanoparticles includes removing platinum atoms from edge regions and corner regions of the nanoparticles and replacing the platinum atoms with atoms of a second metal, such as gold. To cause this replacement, the platinum nanoparticles may be combined with a metal salt in a solution. Platinum atoms from the edge and corner regions react with the second metal quicker than surface atoms from terrace regions of the nanoparticles. The nanoparticles may also have surface defects, such as steps and kinks. The platinum atoms that form the steps and kinks may also be replaced with the second metal atoms. The method includes removing the platinum nanoparticles from the solution after a predetermined time such that the surface atoms on the terrace regions remain unchanged. In an exemplary embodiment, the platinum nanoparticles are used as a catalyst, and the method results in a more stable catalyst.
摘要翻译：制备稳定的铂纳米颗粒的方法包括从纳米颗粒的边缘区域和角落区域除去铂原子，并用铂金原子替代第二金属如金的原子。为了进行该替换，铂纳米颗粒可以与溶液中的金属盐组合。来自边缘和角落区域的铂原子比第二金属比纳米颗粒的平台区域的表面原子更快地反应。纳米颗粒也可能具有表面缺陷，例如台阶和扭结。形成台阶和扭结的铂原子也可以用第二金属原子代替。该方法包括在预定时间之后从溶液中除去铂纳米颗粒，使得露台区域上的表面原子保持不变。在一个示例性实施方案中，铂纳米颗粒用作催化剂，并且该方法导致更稳定的催化剂。
