The Gradiator: Functionally-Gradient Nanocatalyst Reformer Module
نویسنده
چکیده
SOFCs running on jet fuel reformates are attractive to NASA for its uninhabited aerial vehicle and low emission alternative power missions. The US military has interest in fuel cells due to their lightweight, zero emission and low acoustic signatures in strategic zones. Jet fuels, such as Jet-A and JP-8 are already on board in many applications. If they can be reformed and used in fuel cells, military missions can be made more effective. High concentration of organosulfur compounds in these, however, leads to rapid deactivation of traditional reforming catalysts and, their removal through adsorptive methods is not practical. The development of robust desulfurizers and sulfur-tolerant catalysts is a critical path for the use of logistic fuels in powering needs of NASA and Army through fuel cells. We are designing reformers consisting of a functionally-gradient assembly of a nanocatalyst and an agile sulfur-sorbent on an exquisite lightweight nanoporous biomimetic support.

Spreading of Plastic Zones in Functionally Graded Spherical Tanks Subjected to Internal Pressure and Temperature Gradient Combinations
Thermo-Elasto-Plastic analyses of thick-walled spherical tanks made of functionally graded materials are investigated analytically. These tanks are subjected to positive or negative temperature gradient and internal pressure loadings separately or simultaneously. The power law modeling has been used for through-the-thickness variation of mechanical properties. von Mises yield criterion and Elas...
متن کاملCrack Detection In Functionally Graded Beams Using Conjugate Gradient Method
In this paper the conjugate gradient (CG) method is employed for identifying the parameters of crack in a functionally graded beam from natural frequency measurement. The crack is modeled as a massless rotational spring with sectional flexibility. By using the Euler-Bernoulli beam theory on two separate beams respectively and applying the compatibility requirements of the crack, the characteris...

Present paper is devoted to stress and deformation analyses of heated variable thickness functionally graded (FG) circular plate with clamped supported, embedded on a gradient elastic foundation and subjected to non-uniform transverse load. The plate is coupled by an elastic medium which is simulated as a Winkler- Pasternak foundation with gradient coefficients in the radial and circumferential...
متن کاملWater-balance Assessment in a Reformer/Fuel-cell System
Abstract. In PEM fuel cells pure hydrogen is used as a fuel. Due to its low density, the density of its stored energy is low, too. One of the possible solutions to the problem is production of hydrogen from the energy-reach material, e.g. methanol. Conversion of methanol to hydrogen is made with reformer in a steam reforming process in which besides methanol there is also water needed. On the o...

The dynamic evolution of nanocatalyst particle shape and carbon composition during the initial stages of single-walled carbon nanotube growth by chemical vapor deposition synthesis is investigated. Classical reactive and ab initio molecular dynamics simulations are used, along with environmental transmission electron microscope video imaging analyses. A clear migration of carbon is detected fro...
