less stress concentration as well as less space needed

Most suitable shape for gas containers is spherical shape. But it is very costly. After sphere cylinder is most safe container as stresses produced in cylinder are least.

the stress developed inside the cylinder is lesser when compare to other shapes of cylinder and so it is safer than other shape of cylinder

All pressure vessels are cylindrical. Stress gets concentrated on corners/ edges, and the such concentrated stress results in failure. To avoid this, the vessels are made cylindrical to evenly distribute stress. It also has the advantage of easier machinability than other shapes.

Due to stress distribution we made the shape of gas cylinder in spherical shape.

Theoretically, a spherical pressure vessel has approximately twice the strength of a cylindrical pressure vessel with the same wall thickness, and is the ideal shape to hold internal pressure. However, a spherical shape is difficult to manufacture, and therefore more expensive, so most pressure vessels are cylindrical with 2:1 semi-elliptical heads or end caps on each end. Smaller pressure vessels are assembled from a pipe and two covers. For cylindrical vessels with a diameter up to 600 mm (NPS of 24 in), it is possible to use seamless pipe for the shell, thus avoiding many inspection and testing issues, mainly the nondestructive examination of radiography for the long seam if required. A disadvantage of these vessels is that greater diameters are more expensive, so that for example the most economic shape of a 1,000 litres (35 cu ft), 250 bars (3,600 psi) pressure vessel might be a diameter of 91.44 centimetres (36 in) and a length of 1.7018 metres (67 in) including the 2:1 semi-elliptical domed end caps
