Embodiments of techniques and systems for parallel XML parsing are described. An event-level XML parser may include a lightweight events partitioning stage, parallel events parsing stages, and a post-processing stage. The events partition may pick out event boundaries using single-instruction, multiple-data instructions to find occurrences of the “

摘要:
A fuel cell membrane and a method of making the same. The membrane includes at least one non-reinforced layer and at least one reinforced layer. Both layers include a proton-conductive ionomer, while the reinforced layer additionally includes nanofiber-supported catalyst that improve mechanical and chemical durability of the membrane. The nanofiber-supported catalyst is made up of structural fibers onto which an electrocatalyst is coated, deposited or otherwise formed. The structural nanofibers give increased strength and stiffness to the layers that include them, while the electrocatalyst helps to resist electrochemical degradation to the membranes that include them. Such a membrane may form the basis of a fuel cell's membrane electrode assembly.
摘要:
A method for forming an electrocatalyst for fuel cell applications comprises electrolessly depositing a first plurality of nickel particles onto carbon-support particles. The nickel particles are formed from a nickel ion-containing aqueous solution. At least a portion of the nickel particles are replaced with platinum via a galvanic displacement reaction to form a second plurality of nickel particles coated with a platinum layer. During this displacement reaction step, the nickel particles are heated to a temperature sufficient to form the platinum layer. Finally, the second plurality of nickel particles is optionally incorporated into a cathode layer of a fuel cell.
