PureCell System

PureCell System is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand PureCell System rather than just read about it. In short: The PureCell System is a stationary phosphoric acid fuel cell designed, manufactured and marketed by Doosan Fuel Cell America (formerly ClearEdge Power/UTC Power) of South Windsor, Connecticut. Designed for distributed generation and micro combined heat and power applications, it is intended for industrial buildings such as hotels, hospitals, data centers, supermarkets, and educational institutions.

Key takeaways

PureCell System belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PureCell System to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PureCell System from memory before moving on to harder problems.

Reference excerpt

The PureCell System is a stationary phosphoric acid fuel cell designed, manufactured and marketed by Doosan Fuel Cell America (formerly ClearEdge Power/UTC Power) of South Windsor, Connecticut. Designed for distributed generation and micro combined heat and power applications, it is intended for industrial buildings such as hotels, hospitals, data centers, supermarkets, and educational institutions. PureCell System says that its users will see lower energy costs, reduced emissions, 95% system efficiency, 10-year cell stack durability and 20-year product life. It uses a combustion-free process with natural gas and converts heat exhaust into cooling and heating, turning potential waste into useful energy.

Installations On August 17, 2011, it was announced that the PureCell Model 400 system fleet had reached 200,000 hours of field operation. In September 2013, ClearEdge Power announced that its 400-kW stationary fuel cell surpassed 1,000,000 hours of field operation. Today, PureCell Model 400 system fleet has over 12 million hours of field operation. ClearEdge Power’s chief operating officer Joe Triompo said that PureCell System repeat customers include The Coca-Cola Company, Cox Communications, and Whole Foods Market. Other customers include First National Bank of Omaha, Price Chopper Supermarkets, 4 Times Square, Shaw's, GS Power Co./Samsung, St. Helena Hospital, the World Trade Center, The Octagon, New Haven City Hall, South Windsor High School, 360 State Street, Albertsons, the University of Connecticut Diversey, Inc., and Eastern Connecticut State University.

Worked examples

Example 1 — a first encounter with PureCell System

Start with the simplest possible case. Write down what PureCell System claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to PureCell System before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about PureCell System ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of PureCell System

In research: PureCell System appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses PureCell System in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: PureCell System is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fuel cells, so understanding it makes those chapters shorter.
In everyday life: Look for PureCell System outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is PureCell System in simple terms?

Why does PureCell System matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study PureCell System?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
