The invention provides a mineral clay mask and a preparation method thereof. The mask is prepared from the following components in percentage by mass: 5-25% of mineral clay, 3-15% of a humectant, 0.1-1% of a thickener and the balance of plant hydrolats, wherein the plant hydrolats comprise any one of or a combination of at least two of lavender pure hydrolats, cornflower pure hydrolats, rumian szlachetny pure hydrolats, rosemary pure hydrolats or mentha piperita leaf pure hydrolats. The mineral clay mask provided by the invention is mild in property and free of irritation, can inhibit secretion of skin lipids effectively for a long time, cleans the skin deeply, and meanwhile, can condition the skin, inhibit growth of acnes effectively, can make the skin fresh and cool and transparent if being used for a long time, and is smooth and fine.

A system and method for starting up a fuel cell system are disclosed. Briefly described, an embodiment for starting an electrochemical reaction between a fuel and an oxidant during a start-up process includes a fuel cell stack operable to output a nominal voltage during a normal operating condition and operable to output a reduced start-up voltage during the start-up process, and includes at least one balance of plant (BOP) device that supports operation of the fuel cell stack, operable at a nominal output when sourced by the fuel cell stack at the nominal voltage, and operable at a reduced output when sourced by the fuel cell stack at the reduced start-up voltage.

A power supply apparatus for a line connection type fuel cell system includes a power converter system (PCS) control power supply which generates PCS control power from line power, a balance of plant (BOP) power supply which generates BOP power from line power, a regulator which generates PCS control power from the BOP power, a first switching unit switched by a control signal, which directs the line power to one of the PCS control power supply and the BOP power supply, a second switching unit switched by a control signal, which selects an output of one of the PCS control power supply and the regulator to provide PCS control power, and a controller which controls switching of the first and second switching units in response to a starting command.

The technical scheme of the invention provides a full water-soluble compound fertilizer which comprises 3% of potassium nitrate, 5% of humic acid, 8% of ammonium dihydrogen phosphate, 5% of polypeptide metalloenzyme, 1% of surfactant, 2% of nano diatomite, 2% of nitrogen-pyridine and the balance of plant ash. The potassium nitrate provides the nitrogen fertilizer and potash fertilizer for crops, and especially enhances the fertilizer efficiency of the potash fertilizer and reduces the hardening of the soil; the humic acid can enhance the efficiency of the fertilizer, improve the soil, stimulate the plant growth and improve the agricultural product quality; the ammonium dihydrogen phosphate provides the nitrogen fertilizer and phosphate fertilizer for the crops, and the ammonium humate fertilizer can be formed after the reaction between amino groups and humic acid; the polypeptide metalloenzyme provides trace metal elements for plant growth; the surfactant accelerates the dissolution of the nano diatomite in water to form the suspension which is beneficial to crop absorption; the nano diatomite adsorbs the fertilizer to form slow release to some degree; the nitrogen-pyridine performs the function of nitrogen fixation, reduces the loss of the nitrogen fertilizer, and enhances the fertilizer efficiency; and the plant ash can provide potassium and other microelements for the crops and enhance the fertilizer efficiency.

The invention discloses feed for adult yellow catfishes. Every 100g of the dry feed comprises 20g-30g of fish meal, 10g-20g of shrimp meal, 5g-10g of shell powder, 5g-10g of chicken intestine powder, 5g-10g of earthworm powder, 5g-10g of vegetable fat, 10mg-100mg of mineral substance, and the balance of plant auxiliary material, wherein the vegetable fat is any one or more of soybean oil, peanut oil and rapeseed oil; the plant auxiliary material is one or more of bean pulp, rapeseed meal, cottonseed meal, wheat bran and corn flour; the mineral substance is a sulfate mixture of zinc, iron, magnesium and manganese. The feed for adult yellow catfishes disclosed by the invention contains rich animal nutritional ingredients including the fish meal, the shrimp meal, the shell powder, the chicken intestine powder and the earthworm powder, and is very similar to a food source of the yellow catfishes under a natural state, so that the appetite of the yellow catfishes is effectively promoted and the growth efficiency of the yellow catfishes is improved; moreover, the added mineral substance can be used for quickly promoting increase of the yellow catfishes and increase of body color.

A power conditioner includes a main converter to transform a voltage outputted from a power source into a first transformed voltage and output the first transformed voltage to supply power to a power using point; and an auxiliary converter to transform the first transformed voltage outputted from the main converter into a second transformed voltage and output the second transformed voltage to supply power to balance-of-plant (BOP) elements including driving devices of the power source. The main converter includes a first winding to transform the voltage outputted from the power source into the first transformed voltage and output the first transformed voltage to supply power to the power using point; and a second winding to transform the voltage outputted from the power source into a third transformed voltage and output the third transformed voltage to supply power directly to the BOP elements, thereby bypassing the auxiliary converter.
