The performance of a fuel cell is typically measured using metrics such as power output, efficiency, and durability. Power output is a measure of the electrical energy generated by the fuel cell, efficiency is a measure of how effectively it converts fuel into electricity, and durability measures how long the fuel cell can operate reliably. These metrics help evaluate the overall performance and effectiveness of the fuel cell technology.

What describes the amount of thrust created per unit of mass of an engine and fuel?
Specific impulse is the term that describes the amount of thrust created per unit of mass of an engine and fuel. It is measured in seconds and is a crucial factor in determining the efficiency and performance of a rocket engine.
Can liquid fuels be measured by weight?
Yes, liquid fuels can be measured by weight as well as by volume. The weight of a liquid fuel is often measured in metric units such as kilograms or pounds. The weight of the fuel can be calculated using its volume and density.
What s the mass of a cell phone would best be measured in what metric units?
The mass of a cell phone would best be measured in grams (g) or kilograms (kg). These units are commonly used for measuring relatively small objects like cell phones.
Why is jet fuel measured in pounds?
Jet fuel is measured in pounds because it is a unit of weight that is used to quantify the amount of fuel loaded onto an aircraft for safe operation. By measuring jet fuel in pounds, it allows for accurate calculation of the weight and balance of the aircraft during flight planning and ensures that the aircraft stays within its weight limitations for takeoff and landing.
Why is the fuel efficiency measured in miles per gallon (mpg) higher on the highway compared to city driving?
Fuel efficiency is measured in miles per gallon (mpg) higher on the highway compared to city driving because on the highway, vehicles can maintain a more consistent speed and encounter fewer stops and starts, which leads to less fuel consumption.
How is school performance measured?
ppp
How is a fuel cell different from a typical cell?
A fuel cell oxidizes a fuel source, a standard cell is an electrochemical reaction.
How is performance measured in activity-based management?
Performance is measured by a financial or nonfinancial indicator that is causally related to the performance (adding value to a product or service) of an activity and can be used to manage and improve the performance of that activity.
What is Cell diameter is measured in?
Cells are typically measured in micrometers
Is fuel consumption high in Low gears or in high top gears?
generally speaking, fuel consumption is higher in low gears because the rpm of the engine is higher. Performance is measured in kilometers/gallon. You have to consider that cars are designed for optimum performance when you drive at around 80 km/hr. For each car there is an optimum ratio distance/fuel consumption.
How do you test fuel cell?
Fuel cells can be tested by monitoring factors such as voltage output, temperature, pressure, and fuel flow rate. Performance tests can be conducted under various operating conditions to evaluate efficiency and stability. Additionally, performing a visual inspection of the fuel cell components can help identify any signs of wear or damage.
How is cell size measured?
Cell size is measured in nanometers (nm) using a calibrated scale on the microscope objective.
How is the efficiency of a water heater measured and what factors can affect its performance?
The efficiency of a water heater is measured by its Energy Factor (EF), which indicates how much of the energy input is converted into hot water. Factors that can affect a water heater's performance include the type of fuel used, the size and design of the heater, the temperature setting, and the frequency of maintenance.
The performance of a processor can be measured using?
throughput
What is fuel measured in?
Gallons or Liters.
How do fuel level sensors affect engine performance?
A fuel level sensor will not affect performance. Fuel level can due to weight of fuel and accumulated heat in the returned fuel from the engine.
How does the voltage measured across a dry cell ompare with the voltage drop measured across three bulbs in series?
The voltage measured across a dry cell is the total voltage output of the cell, typically around 1.5 volts. When three bulbs are connected in series, the total voltage drop across the bulbs will be the same as the voltage output of the dry cell. So, the voltage measured across the dry cell is equal to the voltage drop measured across the three bulbs in series.
