These assumptions are considered in several problems that use air or water as the main fluids [26].

Table 1 The weight and cost of Bipolar Plates 2002~2003 2004~2005 2006~ weight 90% 78% 75% cost 67% 37% 11%~45% The roles of bipolar plate are[8] (1) to uniformly distribute reactants of H2 and O2, (2) divide the single cell form the stack, (3) current collector, (4) transport water, and (5) cooling the fuel cell.
Fig.6 Stamping layout diagram Sweden's Cell Impact Company is a professional manufacturer in manufacturing metallic bipolar plates.

The iron should be placed in a pot , which should be cleaned well with water and salt.
Bessemer, a professional inventor with little metallurgical knowledge chanced upon the production of steel after he invented a new type of artillery shell that required a gun of steel rather than iron and the crucible steel then available in the 1850s was prohibitively expensive.

It not only achieves the professional standard of SiC on its overall performances, but also has such advantages as reduced resistance deviation and red heat uniformity deviation, increased yield of finished product of sintering, shortened production period and decreased energy consumption.

Also the promotion of new professional figures in cultural economy, no-profit initiatives and educations to the sustainability could carry several positive results.
The Water-paths comprehends the fluvial axes of Amendolea’s Valley because many of them are formally recognized as SIC areas in cartography but in the reality they turned into illegal dump damaging cultivations, animals, society and increasing the hydrogeological risk.

Measured drawing and section of structure has been shown on Fig. 1 and Fig. 2. ground floor of structure has been used for well and water needs of structure has been provided here.
All professional disciplines has worked together, harms that made before has removed during restoration.

., carbon) reinforcing element enhances the abrasion resistance of Mg composite dramatically whose findings indicate that hybridized Mg composites are an excellent product for bids requiring high robustness, modulus of rupture, and tribological components, such as in the automobile and aircraft professional areas.
In quenching, the samples were imperiled to heating at 400oC for one hour in an inert gas atmosphere and let cool in the water in a room situation.

Another approach for 3D face modelling is for professional engineers to design the model using 3D modelling software.

The main objects studied in urban design are the structure of a city and various elements, including a city’s buildings, streets, squares, water features and greenery, edge and entrance, sight corridor, skyline, commanding heights, etc.
First, it requires high-precision professional cameras and also has high requirement for the shooting angle, or the generated scenes may be easily distorted and it may affect seamless stitching; besides, shooting light, brightness and shadows should be as consistent as possible, otherwise, after stitching, color may be inconsistent.
