Week 2 Challenge

1. Compare four different types of fuel cells and state their applications.

Types of Fuel Cells

Various types of fuel cells have been developed. They are generally classified on the basis of the electrolyte used, because the electrolyte determines the operating temperature of a system and in part the kind of fuel that can be employed.

Types of fuel cell	Application	Operating temperature
SOFC	CHP – powerplant	>900 to 1600 deg C
MCFC	Local and larger power stations	650 deg C
PEMFC	Automotive application	~ 100 deg C
DMFC	small and large energy distribution/generation systems since their power production is in the 0.3-3 MW rang	600 – 700 deg C
Alkaline fuel cell	Space shuttle orbiters	< 100 Deg C
Phosphoric fuel cell	local municipal power stations and for remote-site generators.	Up to 200 Deg C

2:
Using a plot with energy density on the X axis and power density on the Y axis, arrange various battery types like lithium ion, lead acid, Nickel Cadmium, Ultracapacitor, fuel cell.
