Diesel/Gas Genset
Solar / Photovoltaic
Proven Technology
But…
Dirty, Noisy, Inefficient
Renewable, Clean and Quiet,
But…
Undependable, Expensive

Renewable and Clean
But…
Undependable, Noisy, Expensive
Today there exists a number of distributed generation technologies, each with their own sets of pros and cons
Most common is the diesel genset-
Pro– economics, proven
Con- dirty, noisy
Microturbines a newer technology- some improvements upon diesel but not far enough
Solar- and Wind promises a “free source of energy” but is still quite expensive and “un-controllable”
We are looking for the combination of Clean, Dependable, and Affordable…
what about fuel cells?

5. Fuel Cells Explained
A fuel cell is an electrochemical device in which fuel is oxidized without combustion to generate electrical energy (direct energy conversion)
Different Types = Different Applications
Commonly Four Types Associated with Stationary Power Generation
current
Carbon +
Hydrogen
fuel
air
Oxygen
positive ions (H+)
CxHy + zO2 nCO2 + mH2O + e–+ Heat
(or)
negative ions (O--)
A fuel cell is electrochemical device for generating electricity
No combustion
Direct conversion (high efficiency)
Essentially C and H in as fuel O in as air produce e, heat, water and CO2
Different Types of Fuel Cells for different apps (Automotive, Stationary, Portable)
Commonly 4 types associated w/ Stationary Power
anode
electrolyte
cathode

7. Competitive Advantage: SOFC vs Solar / Wind
Solar, while clean, is only available 18% of the time on average.
Dirty, grid electricity (“brown power”) is required the other 82% of the time.
SOFC is available 24 hours a day; making it a cleaner, cheaper alternative
