According to energy conservation law, heat conduction and transfer theory of material, a single-cell temperature dynamic model and the temperature model between adjacent cells are built.
The temperature dynamical equation of each control volume Ti, k is as follows: (4) where QM represents the heat caused by material flow, Qamb represents the heat generated by heat exchange between control volume and air, Qex represents the heat generated by heat exchange between adjacent control volumes, Cp is specific heat capacity, m is mass and S is a source item.
According to mass conservation equation of anode/ cathode gas channel, a material flow model is set up.
In view of the key equations upon, a PEMFC stack model is built up by MATLAB/Simulink, as Fig.2 shown.

This surface engineering is widely applied for applications where tools or components are exposed to excessive wear or where, for instance, excellent corrosion resistance is desired.
The initial material state, its chemistry, and the parameters of boronizing have the key influence on resulting thickness, phase constitution, and overall quality of the compound layers.
Also, the hardness variations due to short-time boronizing are presented and discussed, showcasing the options for applying different materials for this thermos-chemical heat treatment.

However, nanoscale engineering of such airstable 3d clusters protected in polymer layers is a major technological challenge, given the readily reactive nature of such nanoparticles.
Thus, engineering the desired air-stable nanocluster, together with independent control of the size distribution, while generating high 3d metal cluster volume filling in the polymer, is a conflicting process.
Hence, in the case of insignificant metal coverage, the Ni atoms, which arrive on the polymer surface produce low sticking due to the very weak interaction between two dissimilar materials.

A simple nanocasting route for preparation of mesoporous titanium dioxide/GCM microsphere Haibin Yang1,a, Wei Rao2,b 1,2Department of Applied Physics, College of Science, Naval University of Engineering, Wuhan, Hubei, China a8895660@qq.com Keywords: titanium dioxide/graphitic carbon; Microspheres; Nanocasting route; Mesoporous Abstract.
Introduction Among various oxide semiconductor, Ti-based materials is the most promising and challenging investigated materials because of its characteristics of high chemical stability, nontoxic, low cost and unique photoinduced electron transfer.
Many different preparation methods have been reported for preparing Ti-based photocatalyst materials.
The prepared materials exhibited cylindrical pores with a diameter of 7.3 nm arranged in a 2D hexagonal fashion and a surface area of 438.9 m2 g-1.
The synthesized materials can be used for many potential applications, such as for use as catalyst/photo catalyst supports or electrodematerials.

Experimental Materials.
The measurement of the adsorption kinetics for the hematite material and the HeCell materials was similarly carried out, where a variable adsorbent dosage was used for hematite vs. composite materials.
