2. Introduction

Thank you for choosing Horizon's T‐2.5KW system as your power generating solution. Based on

Horizon's expertise in modular, redundant fuel cell systems, the T‐2.5KW system is the next step in

simplicity, scalability, modularity and reliability, providing clean, quiet, and reliable power for

backup power applications.

This manual is intended to provide customers with all the information needed to select, install,

operate, maintain, and troubleshoot the T‐2.5KW system.

While there are a number of fuel cell technologies available, the most common and practical

technology for standby power is the proton exchange membrane, or PEM, fuel cell.

The only inputs to the fuel cell are industrial Grade 3.5 hydrogen (99.995% H2 concentration) and

oxygen (air), with the only byproducts being pure water/vapor and heat. As a result, fuel cells are

considered a green technology, making them an attractive solution for installations with emissions

restrictions.

One of the other attributes of a fuel cell that makes it attractive for deployment in many

applications is that a fuel cell produces DC power. This makes a fuel cell akin to a standby rectifier

source, as the power provided from the fuel cell can be directly connected to the site's DC power

bus. In an outage situation, the fuel cell turns on automatically, providing DC power, which was

formerly provided by the rectifiers. DC output also makes the fuel cell ideally suited for hybrid

applications with solar (photovoltaic), wind and battery systems.

The fuel cell is akin to a generator, in that the fuel cell is sized for the power requirement, and can

run indefinitely provided it has a source of fuel. This means fuel cells, when coupled with an

appropriately sized fuel storage solution, can function effectively for long reserve times as a

standby power source in customer applications.

The T‐series system is designed to be a backup power solution for DC power applications within

the transportation, security, wire line and wireless telecommunications, utility, and government

sectors.

The T‐series system is intended to augment traditional DC power systems. A simplified DC

connection diagram is shown in Figure 2‐1.
