1.1 Fuel Cell Description
Fuel cells are electrochemical devices that convert the chemical energy of a reaction directly into
electrical energy. The basic physical structure or building block of a fuel cell consists of an
electrolyte layer in contact with a porous anode and cathode on either side. A schematic
representation of a fuel cell with the reactant/product gases and the ion conduction flow directions
through the cell is shown in Figure 1-1.

Fundamentals of Electrical Engineering I
By:
Don Johnson, From its beginnings in the late nineteenth century, electrical engineering has blossomed from focusing on
electrical circuits for power, telegraphy and telephony to focusing on a much broader range of disciplines.
However, the underlying themes are relevant today: Power creation and transmission and information have
been the underlying themes of electrical engineering for a century and a half. This course concentrates on
the latter theme: the representation, manipulation, transmission, and reception of information by electrical
means. This course describes what information is, how engineers quantify information, and how electrical
signals represent information.

timesAC UPS SYSTEM SOLUTION FOR AN INDUSTRIAL
A UPS system is a vital part in a complex power conversion
and distribution scheme for process control and monitoring.
Evaluating the best suitable configuration for the given
requirements and topologies is a key issue during the
engineering stage for a new application or for refurbishment of
an existing set-up. However, the decisive / determining factors
are multifaceted and linked together. In any case there is no
“one and only” solution. Closer investigations often reveal that
simple and cost effective configurations fulfil the specifications
much better than the complicated “high-end” choice. The UPS
technology elaborated in this paper is based on double
conversion concept with thyristorised rectifiers and pulse width
modulated inverters, which is a state of the art UPS solution for
heavy industrial applications.
