eBook Overview

The human machine interface (HMI) is one of the most well-known and widely used components in control systems and automation processes. The development and deployment of fuel cells are an example where HMIs can be employed during hardware testing and system simulations. 

HMIs are commonly found in portable devices, machines, centralized control cabinets and control rooms, and process control applications. Since the inception of the HMI, the industry has seen engineers constantly innovating new ways to interface with their machines. While HMIs are expected in finished control products, they can also be very useful during the hardware testing and system simulation phases prior to full product deployment.

The development and deployment of fuel cells are an example where HMIs can be employed during hardware testing and system simulations. Fuel cells have become an increasing focus for many industries as they migrate to increased use of clean electricity and clean power. Fuel cells are devices that can convert chemical energy in fuels (such as hydrogen) into direct current (DC). In industry today, electricity is still largely powered by alternating current (AC). Increasingly, things like displays, computers, cloud devices, and electric vehicles all run on DC power, and could, therefore, be powered directly from fuel cells without the need for AC-to-DC conversion. Thus, they would benefit not only from the clean power generation inherent to fuel cells but also from eliminating the inefficiencies of AC-to-DC conversion.

This eBook introduces the concept of fuel cells and how control and automation engineers can improve fuel cell simulation and testing using HMIs running in LabVIEW and similar programs. In addition, EA Elektro-Automatik provides examples of HMI control for both fuel cell system simulation and testing.
