摘要： A hydrogen fuel cell stack has at least two segments of fuel cells each having reactant gas passages. The reactant gas passages of each fuel cell in each segment are arranged in parallel with each other. Flow of fuel cell fluids is in a gravity assisted downward direction. Gravity assisted flow directs water formed in each cell to lower removal points of the stack segments. Adjacent segments are separated by either a separator segment formed as an integral unit with the stack or the segments are joined and an external piping system directs flow to differing stack areas. A cathode flow enters at a first stack end and a hydrogen anode flow enters the stack at an opposite end, such that cathode and anode flows are counter-current to each other. A coolant flow is normally injected adjacent to and flows parallel with the cathode flow, but can also be directed by the piping system to any or all segments in series or parallel.

摘要： Fuel cells are provided that are at least partially resistant to corrosion, including the use of components that are comprised of materials that are at least partially resistant to corrosion. The fuel cells include subgasket materials and designs, involving geometric arrangements of the subgasket that reduce oxygen permeation from, the cathode to the anode side of the membranes and/or hydrogen permeation from the anode to the cathode side of the membranes. In addition to using protonically non-conductive subgasket materials with lower oxygen and/or hydrogen permeabilities, versus ionomeric subgaskets which are protonically conducting and have high O2 permeation rates, the elimination of the microporous layer (e.g., coated onto the diffusion medium) directly beneath the permeable subgasket materials will also reduce production of corrosive species. The elimination of direct contact between the bipolar plate material surface and PFSA ionomer membrane material also prevents corrosion to the metal bipolar plates.

摘要： A fuel cell electrocatalyst layer having increased voltage cycling durability. The electrocatalyst layer comprises annealed platinum particles having an average particle size diameter from about 3 to about 15 nm deposited on a support structure. The platinum particles are annealed at a temperature from about 800 to about 1,400° C. for a time period such that the surface area is reduced by about 20% as compared to the original surface area. In various embodiments, the electrocatalyst layer retains an electrochemical surface area that is greater than 50% of an original electrochemical surface area after about 15,000 voltage cycles in the range from about 0.6 to about 1.0 V.
